If I could find an FM Towns Marty system at a reasonable price--most of the ones I've seen on eBay go for around $899--I'd buy one quicker than you can say "are you nuts?"
Even nuttier: I'm only interested in buying three games alongside said system at this point--Bubble Bobble, The New Zealand Story and Rainbow Islands.
That's not where the nuttiness ends, though. The trio of games I just mentioned are, with a few exceptions, simple ports of the arcade originals. Also, I can already play all three of them on my PS2 thanks to the copy of Taito Legends that I picked up a few years ago.
Still, I can't help but want both an FM Towns Marty and the above-mentioned titles. Here's hoping I never find one cheap enough to make this nutty dream come true.
