Because I already bought Batman AC, Saints Row 3, Battlefield 3, Super Mario 3D Land, and LOZ Skyward Sword. I'll probably buy it next summer when I have free time and less new games, or when the Game of the Year edition is inevitably released with all DLC included.
Because I'm honestly more excited for Fallout 4.
WHOAH WHOAH WHOAH, before you all shoot flames out of your hands at me, let me just say that I tried Oblivion and it wasn't my cup of tea. Fallout 3 on the other hand...
I mean, I may rent it to give it a try, but I'd rather be playing a Fallout sequel right now.
1. Saints' Row the Third, the Only Game Worth Noticing of the month, has just come out
2. I'm poor right now
3. Don't particularly like medieval fantasy
4. Completely single player experience will not have worn out when I get this game three years from now
5. Trying to kill my huge backlog
6. All of the above
Uhm, because I took one look at Oblivion 4 and thought, "Oh my GOD this is gonna take me a year just to see and do everything in this game...maybe I'll just start on something else first, come back to this later..." D*mned procrastination!
That and I've been busy playing Assassin's Creed Brotherhood Twilight Princess. So yeah, my time's pretty tapped. Oh yeah, I actually work too.
