I played Final Fantasy XI years ago. In the game I remember how I was at level 10 and basically just tried to explore as much as I can. I didn't worry about leveling up or doing any quests. That exploration is what was enjoyable to me. I searched on the internet for websites that have all Final Fantasy XI maps and you can view any map and click right on that map to any map that is connected to it. In this fashion you can see what the entire world looks like easily. I enjoy it!

Try that website. I remember visiting the 3 main cities but I didn't get to Jeuno before I stopped playing. I think I ran out of money or moved or lost internet or something I forget. Who else likes world exploration above all else in this game?
