you wanna elder scrolls game that is SUPER LONG but fun af, Find Morrowind GOTY, I have had sooooo many hours just dancing around, seeing the world, and just overall doing the quests which have soo much more of an impact, like if you join a great house, the other 2 great houses hate you because you are a part of a rival faction, and your skills are important to actually rank up, if they aren't high enough, you don't go up, they really make the roleplaying aspect fantastic
one tip if you do: keep a wiki nearby you may get lost
I have no idea the amount of hours I spent playing Morrowind. Apart from some annoying glitches, it is truly one of the best RPGs ever made. Graphics are very dated but at least there are some overhaul mods to fix that.
