I can tell two you which definitely are for kids:
Rainbow Friends (it's pretty dead ngl)
Dandy's World

Creating extremely strong OC'S to make themselves look cool (and even roleplaying with them). Not like I blame you or hate you for that but I regret doing that.

You know how DIFFICULT game making is. You can't learn it off of 1 tutorial. Not even 20. You need to learn scripting, which feels like learning how to talk again from zero.

Depends on which. It's not like ALL aren't scary and if you think it is, it's just your opinion.

I heard they're making a remake with a purple logo
