OP there's a huge difference between wanting a significant other to know you enjoy games and want them to enjoy them too and forcing games onto them.
I'm huge into gaming, but when I first went out with my now-girlfriend of a year (that I also met on OKC) we did coffee, then decided on a dinner date, and over the course of these proper dates we discusses each other and our likes and dislikes. Gaming came up and I just merely said that gaming is a big part of my life, I plan on doing it going forward, but I also enjoy getting out and doing things as well.
This helped so that the first time she came to my place she wasn't shocked that I had multiple consoles and games in my movie case, and some random gaming items around (within reason). We are both comfortable with it and she likes to watch me play to see some of the game stories (LoU, etc).
So, basically, do some standard dates, get to know each other, and just note you like games when you're chatting and maybe somewhere down the road if she likes you enough she'll join in, or at least acknowledge that you plan to keep playing and make peace with it.
On the first date don't jump games onto her, just let stuff like that come naturally.
