I guess, compared to console games, it must be hard to buy the rights to all those old computer games because there was no gate keeper company that took the particulars of all the game publishers and also because the companies often were smaller, often just 3 or 4 people with good ideas hacking away. I guess that's part of the reason why these C64 games sell for €5 and not €4 like the Master System games.
Personally I can't remember any C64 games I would like to play again, but I can certainly remember a whole bunch of Amiga games. I hope we will get those eventually.
Does anybody know if International Karate already has a history of rereleases on other systems or if this is a VC exclusive? Ah, I found something on Wikipedia:
"In 2002, following the retro-gaming trend, Ignition released IK+ for the Game Boy Advance and PlayStation, both of which are faithful to the Amiga/Atari ST version."
"In 2004 IK was be "re-released" as a title on the C64 Direct-to-TV."
