If I enjoy a game, it motivates me to do every side quest and explore every nook-and-cranny. I'm not out to 'win' games or into speed runs. I guess I'm more of a process oriented gamer rather than a results gamer. I'm in no rush to get through the game. So, give me hidden content that rewards exploration or just interesting stuff with no real pay-off other than the fun of discovery and role playing.
