What's with the obsession with putting PSX ports of real-time strategy games on PSN?
I'm ever-so-slightly interested in Ragnarok DS, though I've never played Ragnarok Online. If it turns out well, it'll raise my hopes for MapleStory DS being good as well.
Speaking of DS ports of non-games, KORG DS-10 Plus!
That Data East collection has Burgertime, Magical Drop III, and Heavy Barrel.
