Off topic a bit: Once, me and my friend were super amazingly bored, so we've decided to poke fun at a few people in the modding scene, who at the time wanted Valve to release the source code to the Half-Life 1 engine out of the pure benevolence of their hearts. We set up an online petition, where we formally requested that Valve release it to the public, seriously written and all. Then we've proceeded to spam the hell out of it, impersonating people like Gabe Newell, Mike Harrington, Ted Bundy, Albert Fish, and whatnot else, making "fitting" comments.
An online petition charming at first, but they really don't do much. Companies need financial endorsement before they'll do anything, because that will always be their primary concern, if something actually does attract profit, if it's actually profitable. Nowadays video game companies are very careful to stick to a only what is guaranteed to work, the same basic formula, the successful game franchises, etc. They don't risk anything that will hurt their finances. That's pretty much universal nowadays in the industry, at least for the really successful game companies.
So in short, buy the Klonoa games that were re-released on the PSN if you can. That's pretty much the only vote that will count. Unfortunately, I only have a PS2, I wish NBGI decided to distribute the re-releases on Steam aswell, I'd surely buy them.
