Well okay, that varies by perspective, the actual story is quite condensed and is resolved very quickly, but in terms to game length, Birth By Sleep is roughly on par, or longer than Kingdom Hearts 2.
For example, the average playtime for one episode is 10-15 hours. It's possible to finish in less obviously, but then, it's possible to beat KH2 in under 10 hours as well.
So based simply on the completion of Terra Aqua and Ventus' stories, the game is already weighing in at 30-45 hours.
Add in time spent melding, grinding, journal completing, side-questing, and secret boss fighting, and suddenly the game is much longer than KH2.
And I'm not even touching up on 100% completion for each mode.
