I picked up a 3DO a few years ago. It was definitely ahead of its time, and certainly priced itself out of the market. Wasnt it like $500 when it came out? Then they let 3rd parties build the systems, so you got 3 (i think?) different versions of the system. I have the FZ-10, which seems to be the best of the bunch.
Some notable titles I enjoy playing are Alone in the Dark, D, Another World, Road Rash, PO'D, Killing Time, Monster Manor, Wolfenstein, and a few others. The video quality outshines most of the CD based consoles of the time, so FMV games look pretty good for the time. There is also a really faithful port of Street Fighter, but it needs a 6 button controller, which is a bit expensive.
If you have a chance to get one without breaking the bank, I would recommend it.
