I really disliked the first game. Took two attempts to finish it and that was a pure 'gotta just beat it' grind.
Everything that annoyed me was fixed in the second game. I loved the visuals, the game play, the upgrade system, and all the modes. I'm glad they changed the game up and now I can't wait for the third game. Hell, I even 1000/1000 and didn't even realize till the last mission in vendettas that I was going to.
