Ronith,
My husband (Silvann) and I met through a game as well (for curious types it was a Halflife mod called TFC). We've been together for 5 years now and we have a 2 year old daughter together. Meeting each other was the best thing that ever happened to us. He's the love of my life.
So, yes, you can meet the right person through a game. Love is love and I kind of think that the unique thing about meeting that person online is that you get the opportunity to fall in love with
the most important aspect of a person--their mind--the very root of who they are. Everything else is really just trivial in comparison, isn't it?
Best of luck to you both.
