Feels a little bit like Halo, except that I think this one is more geared toward adults...
I was fairly impressed by this game, and I'm not really that big of a fan of FPS's. The story line of it was actually a little bit better than I thought it was going to be, although, it would have been nice if some of the questions were answered. Maybe in Resistance 2, we'll see.
But as far as this one goes, probably the best thing going for it were the weapons. They are really cool. In the first playthrough, you get your hands on a nice variety of some really cool weapons. Each of them has their own standard or special functions, which makes at least one of them perfect for each given situation. The nice thing about this game is that it allows you to carry all of them at the same time, instead of only allowing you to have two guns at a time...
The gameplay moves at a good pace, keeping the action going for as long as it takes to run out of ammo, then giving you a minute to get caught up on things.
I really liked it, and will definitely play through it at least once more before the sequel comes out (you get new weapons available after the first playthrough). Looking forward to R2.
