So true, I mean Mario 64 is so popular. You'll love this channel on YouTube. He goes so in depth with the mechanics and mathematical equations in SM64 it's absolutely mental.
Kingdom Hearts
The Stanley Parable
Pyre
Sonic Mania
(havent even finished those last two yet but.... good god. They're so fun.)
Undertale
Portal 2. Of all the games I could list, this is the one I'd pick if I could only pick one.
and then Kid Icarus: Uprising. If I kept listing I'd be here all day but these are the games off the top of my head that really struck me in some way and were genuinely a blast to play.
