Divinity: Original Sin 2
Played it through twice. Mile wide, inch deep, and on invisible rails. Iinsane tonal shifts, overly convoluted story in an attempt to hide how dumb it is, characters abruptly talking completely out of character, nonsensical (and bugged) initiative system, multiple completely non-functional and absolutely useless mechanics (crafting in particular). Plus an XP system designed with such mind-numbing ineptitude that it's actually possible to softlock your game by leveling wrong, which they fixed by adding infinite respecs. Complete waste of massive potential.
