I hate how most beat'em ups are like 60 minutes long

Roguelikes
Especially simpler ones like Shiren The Wanderer and its ilk.

Shmups

It is one.
Does that bother you?

Any puzzle game, shmup, beatmup, or single-screen arcade game.

I find it impossible to play them for short periods. I always expect it to be, but then an hour has gone by and then I die and know I should quit but always want to start another run right away anyways. Suddenly it's 3 am. Again.

This.
Any version of it.

You can blow through a Contra: Hard Corps playthrough in about a half hour at worst.

Tetris.

I've played it in spurts every few years where I'll play it 30 minutes a day for a year.
(Especially when I became able to play it on my phone. Tetris is a very good poop game.)
