Not really a fan of P.A., mainly because I've never followed them (so I really don't know their humor and what-not), but after trying the demo, I love this game.
I didn't think I'd put down the 1,600 points at first, but after playing through, I'm really liking it. The combat seems to be very well-done, with some very nice attack mechanics - especially the "stronger" attacks. I like the story so-far, which I didn't think I would.
The dialouge, for me at the moment, is meh.. and I assume that's because I know nothing of the comics (I did laugh at some stuff, but not all that much, yet atleast).
Luckily for me, I got a 1,600 points card with my $75 GC from BlockBuster (thanks to MCR), so I think I might just drop it on this, especially since Bionic Commando apparently got delayed until July now.
For anyone who is doubting it, or leary about the game, defiantly try the demo, it completely changed my mind.
