I fall back on some of my main games - timeless classics like Mega Man, Mega Man X, Starcraft, and Smash Bros. It's worth noting that I have high standards when it comes to buying games. From the beginning of 2007 to now, I've bought 6 games: Marvel Ultimate Alliance, Umbrella Chronicles, The Orange Box, and Brawl, plus the obligatory Wii Sports and Wii Play.
I've occasionally had moments where I'll look forward to a game before its release, then decide "Nah, there's something better I can get," Or "Crap, this game is starting to look disappointing."
Of course, there's the good ol' outdoors to keep me sane. Some of my best spent days involve me alternating between going for a walk outside, and playing Starcraft with one of my best friends whom I've known since grade school.
There's something comforting about getting up at sunrise to go running, then coming home and showering and playing through some Mega Man X or Starcraft while most people are still asleep. The most fun I've ever had when isolated from the company of others. Ahh, good times.
As far as games go, I'm looking forward to Devil May Cry 4 (PC) and Starcraft 2. Then maybe Nintendo will get off their asses and start making a Starfox or F-Zero game for the Wii.
