Ultima VII is the first game I got for my PC (stuck with a C64 until then
), so it obviously holds a lot of nostalgic value for me.
I had played plenty of rpgs on the C64, but I definitely spent more time until then playing NES games, so the sheer size of Ultima VII was simpley mindblowing. I couldn't believe that, other than the guards, every character in every town had his or her own name, portrait, personality, job, and even schedule. I liked how you could go around solving little quests for people all over the place for no reward other than just enjoying the game and learning a bit more about its world.
I played the game on a PC well below the minimum specs (386-16) and it played like a slideshow; the screen would update once every 2-3 seconds. It wasn't frames per second, but seconds per frame. But the game was so great that I put up with it.
Having said that, the combat is horrible and I realized that immediately. Even so, it was still awesome running around with a large party, stumbling upon some brigands, turning on combat mode and just seeing what would happen.
