If I'm not mistaken, they were:
Game Dev Story (iPhone). It's cute. It's casual. It might as well be crack cocaine cut with heroine. I played this game for an entire day when I had plenty of other things to do (or play for that matter). All because I kept saying "Just one more turn" (in this case, a turn was the production of a single game). I hate the five dollars I spent on this game because I cannot ever open the app without devoting hours of my life to it. That's either a ringing endorsement or the nicest condemnation ever created.
Fallout New Vegas (PC). I spent 60 hours in the game and did the bulk of what there was to do. I had fewer problems with bugs than others (or, rather, I was more diligent in my search for solutions to bugs than others) and I found that the game was an improvement in general over Fallout 3. The world was better realized, the characters and places were more interesting and I, as a player, felt like I had more options when solving any particular problem. It was worth my 50 bucks.
Darkstar One (360). It isn't the best space game I've played (by a long shot), but it is the best space game I've played on the 360. It was worth my 40 bucks but I wouldn't recommend it unless you're really itching to play a game that's kind of like freespace, and even then just because that itch isn't going to be easily satisfied with anything new(ish).
