I like the Prototype series. You don't get a great story or a lot of variety in missions, but what it lacks in these ares, it makes up for in addictive gameplay and fun. I like a good challenge. I just beat Bioshock on 1999 mode. But sometimes I just want to blow of some steam and f#$% s#$% up. If that appeals to you, this is the right game. Running across walls, flying to objectives, and blasting a group of enemies to oblivion never lost it's thrill for me, and there are so many ways to do it. I think the Bio-Bomb was my favorite new ability. And this game also does a good job of walking the line between serious gaming and casual gaming quite well. Since the missions are so brief, you can jump in and out of the game for 5 minutes, or for hours. The new game plus is always a nice touch, too. Honestly, if you are going for achievements, the new game plus mode for hard goes faster and easier than the first playthrough. It only took me maybe 10-20 hours of ease to get the full 1000.
