My thoughts:
+just as much fun, if not more, than the inFamous beta
+more game menu music
+temple and ice cave
+the new tank in village level (LOL)
+enhanced graphics from first run
+cinema mode
+shop mode, new perks, skins, etc
+new guns since last time (RPG, ravamped nade launcher, pistola)
+many more game modes
-ice cave is kinda lousy
-no rewind in cinema mode
-melee is still problematic (you should be able to get out of a fistfight without getting forced to take two hits. after all, the first person to land the hit wins no matter what in this case...)
-headshots still seem somewhat worthless
-in elimination, if the time runs out, the team with the most people should win. stragglers should not be able to cause a tie, a la Gears
-shotgun autoaim is ridiculous
-RPG feels almost exactly the same as the nade launcher, only it has a smaller mag, slightly more power, and no dropoff (in which case, the nade launcher's dropoff was reduced. it almost flies straight now dammit)
Spent two hours-ish playing so far all on deathmatch, i'm at lv15. Had a game where I went 35-5 (granted, the other team wasn't very good), and some other games were I went 3:1, but mostly 2:1.
Hopefully I'll get more chances to play today after all my damn classes and workload gets lightened. Maybe with GAF even?
