[PROTOTYPE] is a great game if you life free roaming and just causing mayhem. I rented [PROTOTYPE] and beat it in 3 hours, but continued to play the whole week and got about 3 days of gameplay tacked on to it. It is a very addicting game and fun. If you've play Just Cause 2 and liked it, you'll like [PROTOTYPE].
Its fun, but until you beat it the first time you'll have trouble with the Hunters (A powerful monster). Theres a certain upgrade that one hit kills them. I'm excited to see if they will have a sequel. Also, you don't have to the whole [PROTOTYPE] thing.
it gets repetitive, but it is a good game. theres some flash games that are better (they have new experiences) but once your getting millions of ep and buying everthing and getting 100%... it's horrible... just plain boring.
oh ya, if you didn't pick up "darksiders" yet, do so. it is one of my favorite games very good replay value. one of the most epic post-apocalyptic games ever. and an amazing storyline. only flaw is you have no real close connection with the main character, (like you do with john marston from "red dead redemption". theres another good game, if you don't have that get that also...
