It hit top spot in the UK this week among gamers. Remember, there are reviewers (mainly young hip twenty-something's) paid to critique the games, and often extremely biased. Then there are the actual players like us, in our late twenties/early thirties, or older, who loved the original and doesn't think it has to be the latest example of ground breaking gaming tech to be great.
The game isn't polished, that's the only real issue. Trust me.
