Find a fun single-player action game

Looking for a fun single-player action game. Please don't give us those crappy games to brush us off. I hope this game is around 10 MB (small games aren't fun). I hope the game has class choices, free attribute points, no skill points—you have to practice skills to level up, can change classes, with a level cap of 250. Only a few exclusive skills, the rest you have to get by defeating monsters. Same goes for equipment. There should be dungeons, no main storyline quests, fewer tasks—you have to find NPCs to get quests yourself… and so on. I can't think of more for now. I hope customer service can consider my suggestions. Thanks.
