Xbox 360

what can be done apart from the main story?

I hate this attitude that some modern gamers have, its the reason that most good games are bloated with so much filler. Did we need the triforce quest in windwaker, did we need the indiana jones sections in resident evil 5, did we need the multiplayer elements in bioshock 2 and metroid echoes, did we need 5 sidescrolling shooter sections in Shadows of the Damned, did we need the middle 40 hours of FFXII . NO WE DIDN'T!!!!!

Seriously its people like this that cause 10hour excellent games to be stretched out to 20 hour dull as dishwater affairs.

If you want something extra to do theres pigsy's perfect 10 which illustrates my point.

Best games ever made Metroid Prime, Killer7, FFX, Super Mario Galaxy and Fallout New Vegas by this time next year (as i'm assuming it will be fixed by then)

The game is worth about 10-15 bucks simply for the presentation, facial animations and voice acting alone. However, the combat is pretty simplistic and the camera can get pretty funky sometimes. However, if you can find it for about that price then go for it.
