What I meant was more along the lines of "what would a good beginner kaizo hack be?"
If and when you ever return(since at the time at of this post you are inactive), I think a good kaizo hack to start with would be the "well known" Kaizo Mario World series. I think the best out of all of them is 3 since it's not really that well known and there is some good kaizo level design in it.
Anyway, I'm looking for a new, different vanilla kaizo hack, any suggestions?
Super Dram World does the job perfectly. It's fully vanilla with the exception of the skull blocks, and while it tries to recreate how the original Kaizo Mario originally looked like, hopefully you should get where I'm hinting at. I haven't found any others to suggest at the moment.
Along with Super Dram World, other easy-difficulty vanilla kaizo hacks are SMW Remix, Kaizo Fusion World, Super Panga World, SMW Intrigue, Super Responsible World, Worse Than Kaizo... And technically the first few levels of Cool or Cruel are mostly vanilla too. And there are some other Kaizo hacks on this site. There's also Skill Up Mario, a Japanese Kaizo hack that's semi-vanilla. I know I'm definitely missing some...
1) Banzai Mario World
An interesting gimmicky hack with a lot of great challenges and beatiful palettes.
2) Kaizo Mario World
This hack has some enjoyable challenges, but you only have 5 lives. If you play with savestates, it won't cause many of problems. If you don't mind its aesthetics (like maybe floating/stacked munchers), you should play it.
