Older Games that you Pop back in the Tray

Not long ago (Wednesday night? Thursday night?) I played form Too human coop with a buddy of mine. Had a blast. It's  a fun little dungeon crawl and while the game is far from perfect it really has a pick up and play appeal. And carving your way through wave upon wave of enemy is good times.  Next day at work we got to talking about Mass Effect, and how ME2 is going to be shown in parts sometime in March. We just yapped about how much we loved the game, and how we played different constructs etc.  Same with Marvel Ultimate Alliance.

That got me thinking: what older game do you keep coming back to?  Something that you find yourself popping back into the tray time after time.  If it's an older multiplayer game, do you play for the multiplayer or the SP campaign?  Interesting thought: would you guys consider Halo 3 an older game now? 

I mentioned some of the games above, but truth be told I havne't really gotten into the habit of replaying 360 games. The reason is simple, with a toddler, you just don't have the time to play games like you did before kids. Not complaining at all, it's just hte truth. Before Sunday was an all day game fest: now it's Mommy-Daughter day.  I think it's a step up.  But before kids, on my PS2: I guess it would be either Kingdom Hearts (probably put in 150+ hours in that game easily) and Star Ocean Till The End of Time (probably 100+ hours ).
