To me No More Heroes 2 was a lot more enjoyable than the first. It fixed the major issue I had with the first game which was the boring overworld and the boring grind to the next level/boss (and while that was the whole point of the first game it was just something I was not a fan of). When playing this game I also noticed it was quite a bit easier than the first which I liked, because I could basically shut off my brain as I kill everything in my path, but I also felt like there was never any learning curve like in the first game. I felt like the bosses were at the same level of quality as the first (with the exclusion of the final boss because it fucking sucks). Another thing I really enjoyed with this game is the parts where you played as Shinobu and Henry since they offered a new a new fighting style for them both. The job system was also improved in my eyes with them being Retro style minigames except them being in engine (except the 8th job which was basically the same one that was in the first game).
