Here's my dilemma...

I have been so busy recently working, running errands, and working on my business venture that I haven't had the chance to play any games recently other than a few minutes here and there on my Nintendo DS and Wii. This weekend though, I plan on taking time just for myself, and my games. I plan on pulling all night game sessions on both Friday and Saturday (preferably on my XBox), but I don't know what to play.

I have yet to play Half Life 2 or Mass Effect, finish Gears of War or Halo 3 or Marvel Ultimate Alliance or Saint's Row. These are the games that I own, but I was thinking of buying or renting something new for the weekend. Maybe I can find a copy of Ninja Gaiden II somewhere. I'm also interested in Tomb Raider Anniversary, Burnout Paradise, Dark Sector, The Club, and Time Shift.

I have no idea what I want to play. What's your suggestion?
