few years back i had a mint Xenogears and suik 2....
xenogears grab like 50-80 bucks within seconds of listing same with suik
today i think gears fetches around 30 bucks Suik is hanging around there but i think 50 bucks be pushing it now
These are used prices... I never seen a sealed Suikdoen guide so it either might be worth a lot or people might just think its rewrapped cause i never even recall ever seeing a guide back then sealed ...
