I dunno, enough outlets have dinged it that I think there must be something wrong. Considering this is from the Dead Rising dude, that is no surprise.
Isn't it just 1up and Gamepro that gave the game above average scores? Didn't an EGM reviewer also give it an 8, and some other sites give the game higher scores? I think IGN gave it an 8.5, too.
For the record, I was all over the Dead Rising demo and couldn't get into the game when it came out. LP was not that way.
From what I can gather, most reviews are pretty much stating that it starts out great, but it kinda peters out after a few levels. The multiplayer is solid but not spectacular - other games have better multiplayer and you will probably play them.
The thing is, the game only gets more and more intense with every level. It kept getting better, although the last boss fight could have been something more. Multi is a lot of fun, plus once the U.S. version is out, a patch is supposed to be out to address some issues. Some reviews have also barely even mentioned multiplayer and the various modes it offers. It's too bad that the reviews (none of which are really bad, save for that 1up score) seem to have people thinking this game isn't great. It was a blast to play. If you enjoy blowing lots of stuff up and taking on HORDES of enemies at once, you'll like Lost Planet. The boss fights are also far better than most third person shooters I can think of. The game really does a good job of bringing that old-school boss fight feeling back.
