I'm enjoying Prototype. I like having uber-powers, running up buildings, throwing cars on choppers.
It's fun!!
I also love the upgrades. The onw thing that bothers me a bit is that I was doing an event where I had to follow waypoints and I was so fast and jumping around that I kept losing control of the character and missing them.
It's a bit hard to control right. But I can get used to it and maybe there are upgrades to help me with that.
