1) server will depend... since we are in Asia region. most of us are playing JP server for better Ping. for an exact server name, better browse the ff14 ARR thread and see which u like. as for me, i am on Tonberry server, theres alot of msians there as well as english speaking players, so got not problems

2) whether the game is good or bad is entirely up to the person that plays it. each ppl has their own opinion. as for me, i love the game. nice dungeons , nice mechanics, nice story , even the side quests are nice , and graphics very nice.
3) the leveling in the game is fairly easy as it lets u level every class in one character.
4) ive been playing for roughly 7 months now i think and still planning to play for a very long time
5) buying EU or US entirely up to u. some here are playing on EU cuz the EU topup card is kind of easy to get here. as for me, i am playing using US and paying my subscription via Crysta. the Crysta i topup using my debitcard.
hope this helps u

It really does help me alot! thanks! i think im choosing US ones cause i have debit card too... if paying via Crysta buy more will be cheaper right? Im planning to get my copy from offgamers but currently have no stock... hope can be friends with you when I play... cheers
