The problem with Wasteland is the amount of people who played the original and have nostalgia for the series is a very, very, small niche. I'm 30, been playing games all my life, and it's still before my time. I had heard of it, but being born in '81 when it came out in '88, I wasn't going to be playing a hardcore deep wrpg at age 7. It's the DCharlie's and Chronovore's of the world who grew up on Wasteland and have the nostalgia to back something like this, and I just don't see the numbers being there.
Much easier to play on mid/late 90s nostalgia, since that was a great era of gaming and lots of people had gotten into the hobby by then and many of those people still game.
