Old games get retired. If CH kept up with every single game in existence, no matter how old, things would get bogged down and the backlog would become unmanageable, meaning the latest games would take a long time before they got a trainer. I'm sure you wouldn't want that.
Granted, but from what I can tell the newest version of this game is most likely the final patch they plan on doing. Hell when was the last time this game was patched anyways? A year? Two years?
