I fell into the dreaded, "Games are kinda meh" state for a while. It was towards the end of my GCN's life that this happened. I just lost interest in it. Little by little though, I got back in, bought a 360, & discovered the joy of online pwning. Twas a great day. Kinda like hanging out with friends, only you get to kill other peoples avatars, then trash talk about how much more stupid the other guys are.
That's not to say I've stopped playing solitary games. Assassin's Creed, Bioshick & the ilk have really gotten back into it as well. The fully realized stories, as well as newer gameplay not possible a few years back, make it all the more enjoyable. I also enjoy damn-near-mindless shooters. They make me smile.
