What was the moogle housing feature like? Was it personal? Your opinions, etc
You could decorate your room in many different ways, and gardening was pretty cool. But since nobody else could see your room until much later on, it wasn't as popular as it could have been.
What made the game feel alive?
The social structure. You played one character at all times, gained your own reputation, got to know the people on your server, and everyone depended on each other. You felt like you had a purpose in the game.
It was not so much "alive" like Western MMO's which make the world alive by filling it with NPC's, events and such. It encouraged social activity and that's the main reason why it was so lively.
How cool were chocobos? How did they work? What could be done with them, etc
You could ride them, there was a chocobo hot and cold event, you could raise your own chocobo (of various colors) and race it. The reaces were automatic though so nothing spectacular on that front.
I found out that FFXI servers were JP/EN how did it work out? Was it difficult to get things done? Is it easier to talk now with the TAB feature in FFXIV, did they improve on that? Opinions please~
TAB feature was in XI. The playerbase was quite divided but I played during the JP primetime before the EU version was released and had little trouble. However, it could have been better.
