Really though. What would you be playing, exactly?
Imagine playing those games on a 28.k or 54k connection. If cable or DSL was offered during the PS1's run, it was still exotic, and few could have exploited it's potential. Most likely Sony figured that it wasn't worth it.
I'm pretty sure if the games were on 28k or 56k they still would run pretty good. Having cable would just be a plus. This is the first time I ever thought of PS1 even being online. lol
