I'm pretty excited
Resistance 1 was the reason I ever got into FPS at all. Had so many good times playing online, since everything in it just worked out so well. The game modes, the weapon wheels and the fact that the weapons spawned, etc.
Resistance 2 had some good times too. I played the single player a few times, and I played the online co-op so much I leveled all the 3 classes to level 30. But personally the online competitive sucked compared to Resistance 1, so I didn't play it as much.
Having talked about the gameplay, I think these games have some of the best story-telling (and story ideas). The atmospheres in the game are great at putting you in the main character's position. Resistance 1 sort of focused on a more grim and scarier atmosphere, where Resistance 2 focused more on different environments and scale. Also, the little things like Henry Stillman's radio broadcasts in R2 just added more to that.
Insomniac games is just one of the best developers around and they are Sony exclusive.
Here's to hoping they take the good from both games and make Resistance 3 amazing
