Fair enough.

#29: Hint 4: You use something that looks like a household appliance to fight your foes. It's from a series that already showed up on my list.

#28: Hint 2: Your job is to kill people.

#27: Hint 2: The crossover of the century.

#26: Hint 2: A loved one gets kidnapped and somehow always manages to send you letters with aforementioned pictures. The iconic villain has a bobblehead on those.

#27: Mario+Rabbids: Kingdom Battle

Seems like an extra hint is needed after all for 33. At this point even people that haven't played it should have a decent shot.

33) You spent much of this game in a preposterously tall tower.

Hint 2: You play as the vessel.

Hint 3: Part of a series that has done a pretty poor job celebrating it's 25th anniversary... so far.

Hint 4: The series isn't Pokémon but it does start with P

29) Death by fish.

Hint 2: Malfunction by fish*

27) The person think you are, is actually a member of the main villain group of this game.

Hint 2: He now goes by the same first name as the protagonist of a very long running anime, but spelt slightly differently.

26) Funny without.

25) Possessing people has never been more wholesome.

I don’t know if that happens in WaW, or if there’s a expansion for that game, but you’re close anyways.

Correct.

#27 - Ocarina of Time?

28 - Splatoon 2

Why hasn't this been guessed yet?

#29: Hints: Your arch nemesis sets up a trap for you again. You fight him and his army, that is literally not from this world with a machine that looks like a household appliance.

This machine was build by one of your friends who also made a bunch of other inventions, one of which in particular was questionable because it lead to alot of bad stuff happening in another only loosely related game where neither the protagonist of this game nor the guy who invented all of this stuff show up but a different iteration of the villain of this game does.

This game is part of a series that already showed up on my list.

More hints:

28. a) The company that made this game was known for arcade games and arcade ports.  However, this first entry in their most successful series started on consoles.
b)  There are no sidekicks this time.
c)  The main protagonist is blue.

26. a) This is an arcade game from the 80's that isn't even one of the most popular ones.  I'll try to make the clues easy, because this is not an easy game to guess.  You dig around the board like Dig Dug, but the game uses apples instead of rocks.
b)  Defeat enemies in this game either by hitting them with a power ball or by dropping apples on them.
