Divinity: Original Sin

Turn-based RPG where you control two Source Hunters investigating a murder that spirals into something larger. Combat uses action points for positioning, environmental combos (rain + lightning, oil + fire), and crowd control chains. You'll talk through story choices with your co-op partner or AI companion, sometimes disagreeing on how to proceed. The world lets you move objects, combine items in your inventory, pickpocket NPCs, and sequence-break quests if you're clever. Full campaign playable solo or with a friend online or locally—drop in, drop out. Includes a toolkit for building your own scenarios. Expect 60+ hours if you explore most side content. Works well if you like systemic interactions and don't mind reading lots of dialogue.
