Game completion progress has slowed to a crawl, thanks to Super Street Fighter and Battlefield BC2. 
I'm usually not one for competitive multiplayer... I have a hard time playing games with random dudes, like the whole thing is a little mini anxiety attack waiting to happen.
Add to that the fact that I am mediocre at best at FPS's and I always end up feeling like I'm ruining the game for my team or whatever... 
Anyway, my neurosis aside, I am having a fucking blast with BFBC2. This is the longest I've ever stuck with a game like this. The unlock thing is spaced out really well, I'm always close enough to the next goody or level that it's easy to justify playing another round.  I can live with being middle of the pack most of the time, because when lightning strikes and you have a really good round, it is pretty amazing.
Street Fighter is the same way. Back in the day, at the local 7-11 or whatever my friends and I would play SF2 all day. It's never really been like that again for me up until now. I hooked up with this little tournament group called ScrubSport and have been playing in monthly round-robin's. It's super fun... sometimes you eat the bear, and sometimes he eats you, as they say, but all the people are really cool so far. Getting your ass handed to you doesn't sting quite as bad as it could, and I can actually see myself getting a little better. SSFIV knocks be back down the ladder though, I'm switching characters and it's been slow going so far. i've always been a Ryu / Ken man, but this time I'm going for Ibuki and Cody I think.
