But Buster Bros. Collection - which includes Buster Bros., Super Buster Bros. and Buster Buddies - hasn't been available since the PSone days, and adds a few new extras to go along with its rapid-fire, Space Invaders-with-bubbles gameplay.

Aside from offering seven retro puzzle games (counting the Puzzle Fighter variations, two of which are being released stateside for the first time), Capcom Puzzle World is remarkable for being the first PSP game to let players take their own in-game screenshots, letting you immortalize your victories in jpeg form. Old-schoolers scouring eBay for Puzzle Fighter will definitely want to take notice, but even if you've never played these games before, Puzzle World will be worth keeping an eye on.
