I finished up Red Faction Guerrilla a week and a half ago, so here's what I'll be playing this weekend:
 

• Battlefield: Bad Company 2 (360):  I'm currently level 8 right now with a little more than 6 hours into the multiplayer.  I'm not getting to play this nearly as much as I want to, but I'll have to deal.
• Forza 3 (360):  I'm still working toward 200 Gold medals in the game.  This will unlock the last achievement for me, making it my 5th game to S-rank.  I'm currently 43.8% done the game with 50+ hours of playtime, 5,100 miles driven, 442 victories, and 132 cars in the garage.
  
• Quest for Booty (PSN/PS3):  Bought this on PSN during the Spring Fever sale.  I've been meaning to play Crack in Time, but I want to play through this first.  I think it's a bit too long to finish this weekend, but who knows?  I usually get sucked into the R&C games and can't stop playing them.
  
• Heavy Rain (PS3):  Finally got Heavy Rain through Gamefly after a 6-day delivery.  I've put in an hour and a half so far, slow start, surprisingly relaxing.  I pressed x to Jason with unsuccessful results.  I'm going to try to squeeze in at least 3 hours of playtime this weekend.
