The Sega Saturn definitely has its collector's market and one of the more established import communities. So, how much have you spent on a Saturn game, to rip off all of the other topics of the kind?
For me it was $150 on Radiant Silvergun, which has been the going rate for a long time. I feel like I overpaid, as even though, my initial impressions were good, I grew to really dislike its chain scoring system. I found the scoring in this and Ikaruga to detract from the experience for me. Conversely, I paid $9 for Galactic Attack and like it way better.
