Bayonetta 2 fat cutting
-riding on a demon horse
-a jet shooting level
-fighting underwater with a restricted kit
-fighting in the air with a restricted kit
-a mech that is just really shallow melee combat
Other than not having the universally terrible insta death QTEs (which for anyone replaying, is hardly a deal breaker since you know it's coming), Bayonetta 2 has just as much in terms of lousy gimmicks. Bayonetta 2 simply is easier on 2nd climax, gimmick stuff included.
This notion that Bayonetta 2 doesn't keep a lot of the lesser segments of Bayonetta 1 is a faulty one, at best they aren't as hard out the gate, but they get annoying as shit when you are going for a Platinum run on higher difficulties.
it's also a weird thing to focus on when the bike n after burner segment are 5-10 minute segments versus the meat of the game which is a whole lot of fighting dudes, which Bayonetta 1 does substantially better from player kit, to a more clear scoring system, to enemies that can be launched without witch time or umbran climax, to bosses that can be styled on because they don't just stop your combo, to actually losing magic meter for taking a hit, to enemy weapons actually doing damage (ergo an actual reward for bothering to do a torture attacks), the list goes on of stuff you don't even need to be someone who replays these games to be that invested in the changes, much less someone who is going to be making combo vids n shit.
This stuff amounts to a less interesting battle system when you're learning as well. The depth part is a one sided affair between the two games.
