I still play SFC1 often on GSA (can't seem to play SFC OP online for some reason) but SFC1 is still a fun game to play against people.
I still use a Win98 OS so I don't run into the problems that other people do when they install the game. Yes, installing the game is a pain in the butt if you want too play other people, but its not that bad if you take it step by step.
The thing that scares me is what are we going too do if Taldren/Interplay don't support SFC1, 2, OP anymore? Although I would love to stick with Win98 (like it much better then XP) but I bet MS will force me to upgrade. And I must admit, will these games still be able to run with newer OS's that come out in the future? After all, since Taldren can't make any more SFC games based on SFB rules anymore (heck, no SFC games period!) will we still be able to play these great games?
