Oh and btw, I'll be playing on a PC this time around so I'm assuming it will be a much better experience heh[/quote]

Wait, are you asking us why we play or are you trying to get us to convince you to play?

Anyway:

How intricate are bosses?
Depends on the boss. Some are massive, epic battles that rage on upwards of hours pushing entire armies of players to their max and others are lol-fests that shouldn't even be considered a real boss. However, most of them can be zerg with enough of the right people with the right gear.

How much flexibility to classes have?
Most classes pretty much have their set roles in set situations. However those roles can change depending on the circumstances. But *most* theories and techniques have been tested already so 'cookie cutter' roles are pretty much the norm. But being able to change jobs on a whim should more then make up for that fact.

About how long (days played wise) does it take for someone's first 75?
Depends on you. If you play a lot and know what you're doing and don't mind skipping some stuff, a matter of weeks. If you take your time and just enjoy the game as you go, months to a year. Hardcore grinders can max out in about a month or two from a fresh start.

How balanced is the economy?
Everything is pretty low in price...however this includes things many people would use to make cash. The good items are decently priced and the great items are expensive. However, unlike 2-3 years ago, 1 million gil now is a LOT of money and NPCing items can actually be a good money maker.

IS THERE PVP YET?!??!!?!?!?!?
Short answer, no. Long answer, there has been PVP in this game for a long time it's just that most people don't bother playing it. You have to actively seek out PVP players.

What size of party is needed to kill end-game bosses?
6-64ish? Depends on the event, but most are six member fights.

Also, there's no real advantage to PC over PS2 other then fairly tweakable graphics and some 3rd pt mods ranging from different display plug-ins to full blown bots. But if you plan to bot...I suggest you don't even start playing as you'll be axed fairly quickly.
