I'm pretty sure I can wait the 5 minutes for the game to install.
Cool concept, but I don't really see a need for it unless you're a 13 year old kid who's going to pee their pants because their so excited to play the game.
Doesn't look like it would affect mods. Only change is that it installs while you play, so it's still taking up 4gb of space.
so its really only useful the FIRST time you play? thats incredibly stupid if thats true... i actually always liked the anticipation that builds as you wait for a new game to install
