He is a must have and people saying that John Marston should be instead of Niko. Do some history there could be more than just one Rockstar rep. Rockstar are more Playstation then Xbox. We can have Niko and John Marston and maybe even Max Payne they will all work well. Also people saying Niko dosen't have enough attacks really need to start thinking. There are more than just guns think of some creative attacks like a bowling ball. Also too human? that is just stupid. If you think that Lara Croft should be in the game which is also human then Niko should be in the game aswell.
Rockstar has some neat characters, but not a single one of them would bring any actually interesting attacks to this game, sadly. Furthermore, Rockstar has not really done a **bleep** thing for Sony recently.
