There was always something cool about the way classic arcade games seemed like they could last forever. Sure, they'd eventually get prohibitively difficult, but you always had that feeling that maybe... just maybe... you could play the game forever on one quarter. That's why it's so weird that QIX++, a new Xbox Live Arcade update of the Taito arcade classic, Qix, only has 16 levels. Rather than trying to see how far you can go, QIX++ has exactly 16 levels. It's the sort of thing you could complete in under an hour, and unless you're going to start fiending over your leaderboard position, there's not much else to do.
