Compare to other game out there ...
-The game has more depth
-NO leveling exp apparently so nobody will scream about the leveling curve
-All about completing quests as an individual or as a group
-takes forever to kill a mob despite their recent boost from alpha to beta. I know its alot faster now but it still consumes alot of time just to kill one, not to mention that those mobs sometimes run away for god knows why and you have to chase all the way from top of the mountain to the bottom.
-You can aim and break physical parts of the monsters (not every monsters though)
-Weapons/armors? will break (durability count) so you have to anyhow do the gathering and everything and they consume alot of time as well
-travel distance is very very far, i heard you get to ride chocobo and teleport in latter stage but you can start to train sleep walking earlier just in case. Environment is pretty though if you are eco friendly person.
-Regeneration is veeeeeeeeeery slowwww, only when you wield weapon. Off battle mode, its still not very fast but acceptable i guess.
-Some (*quest?)mobs somehow only appear for you, to avoid killstealing i guess.
-Skills have no awesome animation, which is good and bad at the same time. It makes the action space longer than it should be, considering its fast animation but lacks continuity as it's turn based battle system. In short, you might fall asleep due to the slow battle tempo.
Major playing point is the potential group play experience.
Major let down is how much a time sink the game can be. You wouldnt even notice if you accepted a quest to kill 4 of a kinds of mobs and another 4 of a different kind of mobs and it took you almost 45mins - 1 hour to complete.
Obviously, i need a huge upgrade to play this game when it is released.
