I liked the quirks of the original & enjoyed the sequel, though wished they'd have kept the original Sam Lake character model (good 'not your usual hero' feel to it).
This one... initially the 'hitman' styling of him in pre-release screencaps put me off, yet another bullet-headed character which is far removed from MP1.
One preview said the gameplay itself is very good but the actual story hasn't had as much attention, so now i'm undecided - as much fun as it seems, I need a good story to really enjoy playing.
