Very interesting news from Famitsu concerning TLR. Appearently they really liked it.
Obviously, it's Famitsu which is at times, suspect, but they said the game was typically 40-60hrs long, but took upto 80hrs if you did everything - which would make it longer than Blue Dragon (50-55hrs) or Lost Odyssey (55-60hrs), and somewhere around Tales of Vesperia in terms of length.
For those that wonder about other Famitsu X360 reviews:
TES: Oblivion: 38/40
The Last Remnant: 38/40
Blue Dragon: 37/40
Tales of Vesperia: 35/40
Eternal Sonata: 35/40
Lost Odyssey: 33/40
Infinite Undiscovery: 32/40
Enchanted Arms: 29/40
IMO, it's a pretty reliable list.
Back from the dead, I'm afraid.
