Just out of curiousity, how long do you all play a game until you're satisfied that it's "finished"? I guess this post pertains mostly to RPGs, but it can be for any other game as well.
As for me, if it's an RPG- I have to have absolutely ALL sidequests completed and secrets exposed. I try to get everything out of it that the game has to offer, maybe because I feel like I get more of the story that way or something. It doesn't matter to me how high-leveled my characters are, but if it means beating that ultimate boss, I'm willing to level until I can beat it.
I try to also uncover any and all abilities a character has- but only if it's one that is special to them... if an ability can be learned by everyone, I don't normally pay too much attention to it. I also go for ultimate weapons if there are any in the game, and play any mini-games available (and win all the prizes for them, if they are available) or collect all the cards to a card game, etc.
I guess that's about it. If it's any other type of game, I pretty much do the same- all secrets exposed, but I don't have to be uber if it's not necessary.
How about you guys?
