The first 2 Crackdown games did some pretty fun things. The open-world superhero without being a superhero, in a sense. Being a supercop has it's advantages. I know I had a ton of fun with the games - even if the collectibles were a LITTLE buggy - and by the looks of this trailer, a lot of other people did too.
I love the "100% destructible environments" concept for multi-player and if it holds true, that could be a LOT of fun because bringing down an entire building on another player sounds like something I'd want to do over and over and over and over and...you get it. Check out this teaser trailer because it looks...Crackdown-ey (Which is now the name of my Robert Downey Jr. Biopic).
