PAPA NIER IS BEST NIER! This ugly fucker is better than Brother Nier who is typical JRPG pretty boy. Love Papa Nier! So not always. It's too broad of a question. Are we including Racing games? Platformers? Puzzle games? Sports games? Also it depends on the circumstances of the games aim and goals. Setting and such.
