- using the same buff spell that stacks on top of the other.
- classes that can combine system
- being able to repeat an RPG with all abilities, and not just putting you back to lvl 1 with a ton of money.
- being able to repeat missions and being able to get the best items/most reward money from it
- you can upgrade any weapon and shield to an infinite amount
- Action games or RPG games where you can kill all enemies including the Final boss in 1 hit. It only matters you gud you are or what strategy you used.

The PC multiplay alive? I had it for 360 and it was in the "dying" stage years ago.

customization. any game with lots of aesthetic customization gives me a tight lil boner.

I'll probably get shit for this but

something like Okage, I don't know what its called exactly but I love it

also paper mario ttyd's doopliss level is related to that

(doesn't have to strictly be a setting but anything unique makes my dick hard)
