Anyone play it yet? It requires vista, so make sure you get that first. For those who have played it, does it naturally lag like the original HALO did for the computer? The gameplay was slow no matter what computer you played it on. Funny, I found out that it had to be recalled temporarily because a developer mooned a camera, and put it up as an error message when something went wrong with the .ASS filetype...which technically made the game have partial nudity...
