I was thinking of buying Final fantasy XIV but got some questions before

Is it worth buying the expansion right away? what is it the expansion add? more items? more quests?
if i dont have the expansion will i still be abel to trade GIL here whit player that got expansion?

You could I guess but I'd suggest waiting. The main scenario quests in arr is 100 iirc quests followed by another 100 as a bridge between arr and heavensward. This will take a long time to do being fresh to the game. You can't access the heavensward content until all this done.

This is what I did. I played through the game with my main got him to 50 just by doing main quests and side quests then I did the pre-heavensward quests. Started a secondary class got him to 50 as well. Then I started crafting and gathering to start making gil. Grinded all the level 50 dungeons for poetics to gear up my main and secondary class to ilvl 110 gear. This took me almost 2 months to do casually playing the evenings and weekends if I was home it might be faster for you idk.

So I bought the game got 30 days free. Paid for the next subscription then bought the heavensward when I could do the expansion stuff and got another free 30 days out of it iirc. Another reason to wait is that you can't play the heavensward jobs right away even if you just went ahead and purchased it because you first have to level a character to level 50 in one class before you can take on an expansion job.

Best thing is to wait imo.

I'd get it right away or by the time u hit 50. All quests give exp towards ur 60. But that's just how I did it ^^

Also very interested. Just started playing FF7 again on my PS1.

I got it on install now but its takin freaking 150min to update got some more questions

1. hows the buying and selling gil? is it transfered in game (like diablo 2) or is it at square enix homepage its transfered?

2. allso, what server is "the best" saw that ppl are selling gil for more FG at some servers is it couse its low on ppl or is it thats a popular servers?

Its based on if ur playing casually, hardcore, to role play, etc.
I stick on jenova. It's a smaller server, not as bad of elitists, still able to clear anything needed, n a decent community. Gilgamesh and behemoth are the elitist/raiding servers for NA. Just do a lil research b4 deciding ^^

And it's all done in game. Square looks down upon RMT hardcore.
