I am sure this has been mentioned somewhere in this forum, but after a search I couldnt find anything, so ill risk being redundant: gog.com should get the Final Fantasy series (7 in particular of course) as a part of their catalog. I would buy them all.

Firstly, vote for it on the wishlist!
Second, I think only FF7 and FF8 are available for PC (I happen to have them both).

Only 7 and 8 are available for PC (some of the crappiest in the series), the rest would require SNES and NES emulators and I don't think Nintendo would appreciate that very much.

Also, Starflight. That was an old old game but still a good one.

Final Fantasy XI is also available on PC.
Also, FF7 and 8 do not equal good, old games.

Well they're getting on a bit now (assuming the PC release wasn't that far behind the console one) and good is rather subjective. Personally I think FF7 was a steaming pile of poo that everyone seemed to mistake for rich, tasty chocolate pudding but then I hold the same opinion for rise of the trisad and that's scheduled for release here...

I actually liked FF7, but it was the last JRPG I liked. Everything after that just seemed like a poor copy with better graphics. Considering it is a royal pain in the ass to get FF7 running on a modern PC, I would actually like to see it on GOG. It does fall under some people's definition of good and it certainly is old (PC version released in 1998), so why not?

As cool as it is to talk about games like this, if you really want to let GOG know that you would like to see a particular game available from them, just vote for it on the wishlist
