Anyone looking for a significant other that also games? (raising my hand, me me)
If yes, where have you tried looking?
For both our sanity, it simply works better that we don't share everything. Is your significant other a fellow gamer?
As far as D&D and other table top role-playing games are concerned, yes she is.
If yes, what do you like about gaming together?
We enjoy being able to bounce ideas off one another, discuss how sessions went and talk about role-playing games in general. It can turn into quite a lively discussion when we both get excited about a certain aspect of a game we just played, or the possibility of a game we will be playing. My SO enjoys discussing character traits and personality, doing research into her character(s) in order to present a more believable facade.

This is not relevant to me, obviously, but I found my SO in high school. Granted, we didn't see each other for almost three years before I moved back to my small town. We've been together since. Have any high school crushes you could look up?
Is your significant other a fellow gamer? If not, does it pose any problems for you? If yes, what do you like about gaming together?
My wife is a gamer, more towards video games then tabletop. She'd like to do the table top, but since we have two daughters (neither to the age to game themselves), she watches them while I game. I very much appreciate that she is a gamer, and understands that I need my time for gaming. Nearly every session I'm reminded of how awesome my wife is, because contrary to my own two of the other players have significant others who are definitely not gamers. Both of them usually have to leave early, and one often isn't even able to come. It seems even though our group meets regularly every other Sunday, their significant others seem to purposefully schedule things to prevent them from coming. Whereas my wife actually enjoys that every other weekend there's 7-8 people camped out in the basement for half the day.

Having a quick kiss during snack breaks?
Honestly though, when we game together it's not much of a deal. At that point I'm not really thinking of him as an SO1, I'm thinking of him as the player behind that damn cleric that isn't giving my brute the heals he needs.
That said, when I GM for him I have to make my GMing style a bit more transparent so as to avoid accusations of bias. 'course, he's an all-right guy (why else would he be my SO?) and I game with friends, so that's not much of an issue anymore, but it's never fun when you get yelled at when you get home for splattering his silly rogue across a room full of traps.
So I guess the best part about gaming with my SO is that, for RPGs at least2, I know I can count on at least one player (or one other player, if I'm not GMing) being there.

1Sex Object or Significant Other. Both apply, really.
2He's not as interested in some of the board games I like, such as PowerGrid, Agricola, and other low-randomness, high-planning games. Not to mention that some games I can't play with him because it gets too vicious (Illuminati is one such game).
The good thing is that I'll use lots of terms derived from games and its easier (and seems less crazy) to explain to someone who understands. Also, its good when we can play games together so that video game time isn't taking away from spending time together. And even solo game time is better since she understands the appeal and has her own games. Also, its good to have someone around to play 2-player games with.
So there's definitely benefits to having a SO who also plays video games. I've never put it high on my list when looking, but it seems to always come up with the people I actually dated. But I think that gaming has become so popular, its hard for someone to completely hate all forms.
I don't think its a deal breaker or anything. I definitely do not consider my wife a big game person. She'll comment about how her fingers get tired or she gets really nervous during games.
But if you are searching, I recommend what I'd recommend to anyone who wants a SO with a particular interest: just do that interest in public. If you want someone who plays games, go to game stores and play their DnD games or go to a Magic tournament (girls always get hit on at Magic tournaments). There's stuff like arcades and conventions. Just have fun and you should meet people. Or if you're not so outgoing, try the internet. There are plenty of good dating sites which could help you. OkCupid is lots of fun and most importantly, its free. I also know people who found SOs (many serious instances) through Chemistry.com and even Criagslist, so I guess those are all options.
But sometimes you can just find someone and then later realize (or nurture) the gamer aspects in them.
I'm not shy and I do go to game cons. I've done the online dating thing. It's not really that I have a problem getting dates. I just can't seem to find a gamer that I'm interested in that actually lives nearby or that relocate their life.
I also wanted to see if it really mattered if I had a gamer partner by seeing how others felt about this. Not that anything said here would cause me to make any decisions about dating but just to get feedback to see if it's really as important as I'm thinking it is 
I have met a wonderful woman, and would like to be closer to her, but unfortunately we're several states apart and my schooling requires at least 2.5 years of me remaining where I am. So we're remaining "pen pals" for now. She has played D&D in the past, and has expressed interest in playing it again. She also plays WoW, even more than I do. Someday, I hope to introduce her to 4e. Someday.
Before I met her, I would have replied that my "SO" being a gamer was a requirement, yes. I had tried looking mostly at local gaming events, but being stuck here in the bible belt of PA, there are practically no events within reasonable distance.
Currently, I'm not looking for a "significant other" but I am looking for other gamers. I've only been in PA for a year and haven't found many. See the preceding paragraph for why :P
It's important that you respect all aspects of each others' lives, and are willing to at least listen. No relationship will survive very long when "This is important to me!" is met with "Don't wanna hear about it!". The more stuff you have in common, the easier it is to be a team. And, to be blunt, being a "team" of two is what makes a romantic relationship work.
My wife isn't as into gaming as I am. But at least 80% of what I do she at least is willing to try, if not enjoys. Sometimes it's hard to tell how much of "playing a game together" is a way of spending time with me doing something I enjoy, and how much is doing it because the activity is inherently enjoyable to her, but it doesn't really matter. Conversely, I'm not very into gardens, but I take pleasure in wandering around her garden with her or talking over her plans because its something that she cares about.
We play D&D, Agricola, Settlers, San Juan together, for example. In the past, we played through the entire Neverwinter Nights computer game together and played Starcraft together vs computer, but she finds that she hasn't got as much time or attention for that with the young kids and would rather spend it on face-to-face stuff. She doesn't like Star Fleet Battles, or pure wargames, or stuff that's just rolling lots of dice, so I have other friends to do that stuff with (in what little time I have spare after work, being a father/husband, church stuff, and housework/exercise/etc).
Summary:
* it's good to have things you care about in common
* you have to build your relationship around your relationship (and being a team, not just liking each other); a shared hobby isn't enough to sustain it, and a lack of one isn't fatal as long as you can be at least interested.
Some board games and a bit of MTG now and then but never a pencil and paper game like d&d or the like.
Doesn't bother me. She's polite when i recount a sessions amusements or agrivations and she doesn't ride me about spending money on the hobby, so it's cool.
