now that sounds very good..
okay, read through it.. i aprove of that bigtime. cross console gameplay, if they can trully achieve no lag is perfect. games that you're interested in, but only come to a ps3 for example, played on the pc.. superb. if this is really priced well and the games arent expencive as hell, it'll work.
and unless you can make your own server, it'll cut down on piracy 100%. the only problem would be stealing of user names.
one more thing.. you can play this in window mode, because it's essentially just a video on your computer, you can chat while gaming and not bother with switching windows
