Awesome world, but not much else.
But other than that, I found that gameplay a little bit lacking. But several times, games which lack gameplay make it up with their story and graphics. This is one such game. I wish there was more to do in the city, although I think that stopping enemies from respawning in an area when you do the side missions is a pretty cool idea. I just wish there were some other things to do too.
Story is good but one gripe is that other than Zeke and an ex who hates you for most of the game, there aren't many characters, or people who you would care about.
All in all I would advise you to rent it, finish it twice, get all the trophies, and return it.
