I picked Strider up on Ebay recently for $43 which is a little cheaper than usual considering it was a US seller. $50 is typical, sometimes it goes for $70+.
I like ACD Strider. It probably has something to do with the fact that I've never played any of the other Strider games or ports before so I didn't have expectations that were let down. I have foggy memories of playing 8-bit NES Strider for about 1/2 an hour when my friend rented it one day.
Once again, I like it. It's a good action game. I also like using my Arcade card as much as possible.
