One thing that has alway perplexed me about PC gaming is the size of the installs compared with consoles. For example, Oblivion on the PC requires a 4gb installation, whereas on my 360, you just put it in the drive. Doom 3 was another example, again it was a 3 - 4gb installation, whereas on the Xbox it just runs. The DVD drive on my PC is faster than the Xbox, it has more memory, a better graphics card, etc, so why can't I just run it off the DVD? Any one got any thoughts?
