Any Phantasy Star Online game will easily become an addiction for me. I've been drawn in to every single one of those damn things except Episode 3, which I skipped out on.

Blue Burst came out this summer, and that was the worst of it. I spent at least half of my waking summer hours playing that game. The game got hacked to hell, just as all PSO games do because Sonic Team is incompetent, so I no longer play it.

Was it a bad decision in retrospect? Probably not. I really enjoy PSO.
