Well, I just got my first ever disc-based video game system last night!
I just got a region-modded PCEngine Duo from Keith Courage.
The U.S.-released Turbo CD games that I already have are as follows (all CIB):
Addams Family, The
Buster Bros.
Cosmic Fantasy 2
Dragon Slayer: The Legend of Heroes
Final Zone II
Lords of the Rising Sun
Magical Dinosaur Tour
Might & Magic III: Isles of Terra - with map!
Prince of Persia
Sherlock Holmes Consulting Detective Vol. 2
Sim Earth: The Living Planet
Valis II
- I recently picked the above up in a lot with some HuCard games and some PCEngine HuCard and CD games as follows (all CIB):
Bloody Wolf
Bomberman '94 Demo
CD Denjin (Super Air Zonk)
Detana Twin Bee
Double Dragon 2
Dynastic Hero
Gradius 2 Gofer
Gate of Thunder
Godzilla
Image Fight
Kiki KaiKai (Pocky & Rocky series prequel)
Kunio Soccer
Kunio Kun Dai Undokai (Crash and the Boys Street Challenge, I think)
New Zealand Story (Kiwi Kraze)
PC Denjin (Air Zonk)
Side Arms Special
Strider HiryuuShubibinman 3 (Shockman 3)
Super Darius
Super Star Soldier
Violent Soldier
Wonder Momo
Wonder Boy 3 Monster Lair
Zero Wing
If anyone wants to give me some ideas for which games I should pursue next (although I plan to be busy playing the above), I'd love to hear them. I have absolutely no experience with any Turbo CD games or PCEngine games other than online reviews.
