Specifically, I'm addicted to the five-minute "championship" mode that serves as the centerpiece of this Xbox Live Arcade follow-up to Tōru Iwatani's arcade classic. (There's also two, 10-minute "challenge" modes and three "extra" modes, one of which lasts for five minutes and two that last for 10.)
Honestly, it's impossible for me to play this mode just once. That's what I mean to do, at least on most occasions, but invariably I end up telling myself, "just one more time," as soon as the game's clock hits zero.

Despite all of the time I've put into Pac-Man Championship Edition thus far, I'd hardly call myself good at it. I improve a little each time I boot it up, though, which is part of what keeps me coming back for more. The other part? It's simply a blast to play--even when I miss my high score by a wide margin.
I'll post more in-depth impressions of the game (likely in one of my "somewhat gay" reviews) soon, but in the meantime just know that I'm enjoying the hell out of it and that I heartily recommend it to anyone who has a PSP or an Xbox 360.
