Exactly why I bought an Intellivision system, and only plan to get the games I played on it as a kid. My favorite game was Thunder Castle, so it was my first (and currently only) purchase so far. I don't really have much interest in collecting for the system, so I won't be purchasing games that I didn't play or don't remember, nor do I have any interest in homebrew games for it. I only purchased the hardware to relive the full experience, not "new and exciting" experiences, and not as a collector or hardcore enthusiast. I think I'm probably in the vast majority here as well, where the ultra hardcore "gotta have everything" crowd is a lot more niche. Not saying the market isn't there, but it's small, and raising $100k for 3 titles that run on the PC and have little more than updated graphics is a long shot.
