Cult Classics

Divinity II: Ego Draconis

I don't really know if it fits your "cult classics that nobody knows about but are super awesome!" tag, as I'm pretty sure some people know the game. However, it does fall into the "Games that reviews screwed but are super awesome" category.
For those who don't know about the game, it's a RPG on the tracks of Kingdoms of Amalur where you can allocate your skill and stats anywhere you like w/o taking a class path. The base-game ending was completely "What the heck is this" but the complete remastered game + expansion manage to give it a proper ending.
