My favorites are my favorites because I keep going back and playing them, or I've already played them to death. I can go for years without playing Zelda alttp, but I'll still remember where all the heart pieces are. I'm not talking about games I just do quick casual plays of either. Some games I won't beat, but will just play with the idea of meeting some arbitrary challenge or goal in mind. In Double Dragon for example, I don't knock Abobo off the conveyor anymore but will fight him instead, or in the cave I'll jump down into the first pit just to fight the Ropers with the boulder. The best part is the wall. These days I just think it's hilarious when it soaks up all my lives ending my game.
