my experience with onlive was pretty bad the first time i tried it, but my isp upgraded recently so i bought red faction armageddon and gave it another shot during that "buy any game for $1" facebook promo they had
it still wasn't optimal, but there was noticeably less pixelization and the input lag wasn't nearly as bad as it had been before, so the experience will likely get much better (but never perfect) over time
i guess this is about the best anyone who likes playing older console games and bc can hope for going forward, the alternatives are spotty hd remastered releases or nothing at all
i'd imagine there'll be a gakai app for vita at some point, and considering there would never have been any ps2 bc there to begin with, i guess that's...okay?
