Out of the 7 PSP games I've purchased (Lumines, Ridge Racer, Metal Gear Acid, Wipeout Pure, Twisted Metal, Puyo Puyo Fever, and Mercury)
Where did you find Puyo Puyo Fever? I haven't seen it anywhere and didn't think it was out yet. Also, what do you think of that one? Worth it?
As for Mercury, it was one of the games that sold me on the console in previews. I wish I'd read your impressions before racing out to get it today. I've only played through some of the tutorial levels and can already see the load times being an issue. If this game gets as hard as you say, I'm going to be irked.
