-Choice and consequence, what you do in the game has tangible effects
-Meaningful companions+quests
-No voiced protagonist
-Blank slate protagonist
-Weapon durability, spell crafting
-Skill requirements for joining factions, no joining Mage's Guild if you're bad at magic, etc.
-Hire dedicated writing team, make real efforts to improve (Larian did this and the story improved lots, heard the first D:OS story was dumb, 2 fixed all that), don't let Emil Pagliarulo anywhere near the writing
-Dynamic seasons, weather changes based on date
