Played the 360 demo, had terrible connection issues.
Was going to play the PS3 version but now can't.
Do I care about this game enough to buy it? No. Nowadays, I tend to only buy games new if I have played the sequel, the last new game at full price I bought before Pokemon Black being Halo Reach. Everything else I have bought as been pre-owned. The only exception of this is when I play a demo which gets me interested in the game, Just Cause 2 being the last game I can think of.
I know a lot people say demos are pointless but at the end of the day I am not buying this game simply because nothing about it has appealed to me enough yet, a demo may have been enough to make me buy it.
