1. yes and No : explanation Yes) I love the game and nostalgia and music and some of the dungeons and (No) A lot of things are the same, everyone is the same especially gear nobody can say they are stronger or say look at my sword or my armor and people would be amazed and say where did you get that or lucky you got the drop and that armor and weapons are outdated before you finish a set.
2. I played original FFXIV then cancelled due to bugs and moved to FFXIV ARR since beta.
3. Yes WoW to this I go back and fourth when I get bored or have nothing to do in each game.
