Well, I've played and finished Phantasy Star 2+3, Shining in the darkness, Shining Force 1+2...and almost finished Landstalker. When it comes to pick a favorite I guess I'm kinda stuck....they are all great and I still play them.
But there's something special about the Phantasy Star series - which I played first - so I guess I'll have to choose them. (haven't played PS4 though)
The Smash Pack emulator is not bad playing it on the Dreamcast. This way, you can still use your TV to display instead of computer monitor, or computer monitor if you have a VGA adaptor. The drawback is that you have to master the CD yourself.
