Well, I'll be honest that I haven't read the other girl's responses, but here is mine based on experience. Hopefully you'll take the time and read my lengthy response. ;)
Gaming is a lifestyle, as I know you're aware, which means that you will eventually have to find someone who will compromise with you on your gaming habits, regardless if your significant other is a gamer or not. One of my ex boyfriends was an avid gamer like myself; however, his world revolved around his xbox and was an escape for him. He used my xbox, so I rarely had time to game and have fun like I did as a single lady. I ended up picking up WoW so he could use my xbox to play with his friends. Let's just say I lived, learned, and got rid of the loser.
On top of that, I am usually very flirty because that is just who I am. I love to banter with the best of them and enjoy my time online. I have confidence in myself that I don't need to show people pictures of me to reflect the fun and vibrant personality I share with those I game with online. However, if someone wants to see me I direct them to GTP (which is on my gamer tag profile). When I had a boyfriend he would be livid that I was so flirty, which took all the fun out of my gaming habits. I love to trash talk when I play and make lewd comments from time to time. He, of course, found it disrespectful to him. I understand his point of view on things, which is why I ended up slinking off to play WoW instead of fighting for time on the Xbox.
So, in essence, yes I would love to date someone who is a gamer because the lifestyle is there. However, I find that one has to exercise a lot of compromise in order to enjoy previous gaming habits. You'd have to deal with a lot of guys hitting on your chick or them saying mean things to her on xbox live. Yes, she could easily handle it on her own on xbl, but the natural protective instinct (should) kick in. Two systems would be in order and internet sharing would have to be easy. Also, one would have to purchase two games on a lot of systems - this especially rings true if you're living together.
I thrive off of remarks, just like I do in real life. When I talk to people one on one I expect respect, but when I am in game let the remarks fly because I'll spout them right back. I love when my adrenaline gets pumping when I play a great FPS. I love to gain admiration after I kick someone's butt in a match or I get asked to party up so they can boost my bottom to a higher level on a game. I don't mind using my feminine wiles to get what I want. :D (By wiles I mean flirty behavior!)
In the end it's easier to be a single gamer girl. I have a hell of a whole lot more fun gaming single than I do in a relationship. I can go to midnight releases, stay up playing as long as I want, party chat with all my guy friends without fear of making my boyfriend jealous, and spend my money on the type of gaming equipment I want.
Now, if XBL were completely out of the picture it'd be nice to have a gamer boyfriend who enjoyed RPG games I could watch him play and vice versa. My sister and I bonded playing RPG games together through our teenage years. My first official boyfriend bonded over Zelda Ocarina of Time and Halo 1.
