It's getting to be like that old game, what was it? Duke Nukem? Everyone loved it. And the writers kept promising more. But although some new versions did appear (one was a side scroller, IIRC), years went by and eventually everyone lost interest. And the technology advanced so quickly that before a new version could be issued it was already obsolete and maybe even unplayable.
I just wish Forgotten Stories weren't coming out on Steam (if it ever comes out) I suspect a lot of people, esp. avid gamers, have 'issues' with Steam.
