Hello,
@Saturn : Good point, I made a mistake. Fixed now.
@Gazereths's : You're right. I've checked and only MGS2
ubstance has been made for Xbox. And I've added FF:Crisis Core
@Workshed: This one, I've never heard of it! After some research, it appeared it also been released in Japan on PsOne under the name Policenauts. Policenauts got some improvements and is not sensored as SEGA CD version is but... it's all in Japanese. So I added both ^^.
Thanks you guys for all this information. It helps a lot
