Fair enough. I was thinking in terms of systems people may have heard a lot of great things about, but never got to experience first hand, rather than strictly nostalgia about stuff you actually played 30 years ago and still have faint memories of. But perhaps commercially nostalgia wins big time over curiosity with products like these.
Yeah. The sales figures bare out that people respond to big name games versus platforms (big name or otherwise). The problem with something like the PC Engine, is no matter how great it is, there really aren't any games that people would necessarily recognize (and by people I mean the average person, not necessarily core gamers). Among its other issues, I think that's perhaps one of the problems with something like the Retro-Bit Generations. It's the kind of thing that if executed properly would be of interest to gamers like us, but there's very little on there to appeal to an audience outside of that.
AtGames just secured the rights to some big name games (not announced yet), and it's the kind of IPs that will make anyone take notice. At least from the perspective that I'm watching from, that's the smartest strategy if your company name is something other than Nintendo.
To my mind, there are only a handful of classic platforms that will sell well to the general public when mixed with the right games, including arcade, Atari 2600, NES, Genesis, SNES, PS1, and N64. There are others like Neo Geo that I think could survive on lesser name recognition, but higher game quality, and something like the Dreamcast, that might be able to survive on Sonic and a few other notable franchises (Crazy Taxi for one), and the wave of gamer interest in revival of the brand to help drive wider sales.
