How long did this game take you to complete your first time?

Some 60 hours.

around 30 hours, i didn't do much side stuff.

Around 40 hours, without doing any sidequest etc.

around 65 hours

60-some hours, and that's after having just replayed it.

If you just follow the main story, and don't spend too much time grinding, you're looking at 35-40 hours of gameplay.

You could easily spend 100+ if not 200+ hours trying to "complete" this game, though. Ultimate weapons, Dark Aeons, rare items for customizing armor/weapons and filling up the sphere grid for those really tough fights in the game outside of the main story.

About 100-200 hours (i did ALL the side missions!:D)

10000000000000 hours.
