One of my first computer RPGs I played was Interplay's Lord of the Rings. Obviously the story there was a little more linear than yours, but still the world felt huge and there were lots of places to explore off the main path. That's the thing I appreciate about your games.
A lot of commercial RPGs seem more combat-oriented with no story or purpose behind it, and no opportunity to explore - just one battle after another. That's not for me. Battles are fine, but there's so much more to a good RPG than that. I enjoy exploring your world and finding hidden secrets, talking with the characters and being surprised by unexpected plot twists, going on a good variety of quests, solving puzzles, etc. I also enjoy the character development. I love it when I can get alchemy up to a high enough level that I can start hunting for ingredients to make an awesome super-weapon, or build up a high weapon or elemental skill that will allow me to eventually mow down lots of enemies with ease. Now, that's all fun!
