So, have you played any of the classic games aside from the main four? There's PS Gaiden, PS Adventure, and the PSII text adventures.
Out of those, I've really only played PS Adventure. I messed around with some of the text adventures once, but didn't get very far into them. I couldn't ready any of the Japanese text, and those games seemed to be nothing but that. I was expecting them to be very much like PS Adventure, but to my surprise Adventure had a lot more graphics to it .
One of these days, I might try the fan translation of Gaiden.
