An incredibly evil game that involves keeping track of grains of sand in your pockets and crawling about forest floors picking berries.
And yet, for some reason, you actually want to do these things. In between pwning goblins and traveling to alternate universes to battle demons that is. It's incredibly addicting and fun. I'm going to take this rental back to the store and NEVER NEVER rent or buy this game again lest I never see daylight again.
Additional note: Some parts of this game are actually fairly scary and gory and disturbing, not for the kids.
