Tower defense games. I feel like I "outgrown" it. You set up your towers and then you sit there watching the game unfold without doing much yourself, just praying the tower dish another hit before the minion go through. I feel like I'm not playing the game, rather the game is playing itself.
Also, card games. Holy hell devs, we used cards when didn't had video games, why the hell did you put the cards back there? Why make cards out of demons, spells, and what not when you can actually make the dam demons and spells? It's just lazy for me.
