I'm purposely avoiding buying the 360 version because of the nonsensical exclusive DLC bit and went with the PS3 version instead. Childish, perhaps, and it won't do anything in the long run, but it's still my tiny form of revenge.
I'll get it for PC in the GotY version. By the time it's released again some great mods will be out for it.
For that matter, since I've heard the title reuses textures and models from F3, they should be rather easy to mod into New Vegas. Can anyone confirm/deny?
