Depends on the game. other than RPG's I usually just mess around with them a little bit, might put it on the backburner for a few days and go back.

on RPG's it depends on the game. The older FF titles/Chrono Trigger/SNES era I usually get through them in about a week. For newer FF's/Xenosaga/ps/ps2 era I can really get into them for hours everyday and really immerse myself into their worlds.

If the random battles are getting annoying i'll rush through the dungeon, if not i like to explore and get all the treasure i can.
