Huge "guilty pleasure" still to this day, as they say, is Spyro the Dragon. I've played those games about fifteen times each. I can't help it. It's a comparably simpler game than, say, the Final Fantasy saga but I still like it. I also have a ritual for playing: It is absolutely vital for me to pick up all the available gems and eggs/orbs in a world or level before moving on. Otherwise, I feel as if there's something wrong.
