In a behind closed doors meeting at this year's Tokyo Game Show, Hironobu Sakaguchi revealed that his upcoming epic will truly fit that descriptor. Hot on the heels of the three DVD long Blue Dragon, Sakaguchi informed the crowd that Lost Odyssey will span a massive four DVDs. The game, which uses a mixture of CG and real-time cutscenes, will last roughly 40 to 50 hours.
CG cut scenes in it most likely but just like FF7 I wouldn't have a problem swapping discs.
EDIT-
Just skimmed through the 1UP preview summary and it seems that the main character has alot of dreams, that are CG scenes, during the game that are long so theres your answer.
Blue Dragon had 3 discs and there wasn't that many cutscenes. I'm sorry, but 4 discs for a title this generation is ridiculous. When is it too many discs? 5? 10? 20?
ps3 next gen 1 disc
360 last gen 3+ disc
ps3 rules
But I find myself being more excited about this title than I am the Final Fantasy titles coming for my ps3. Maybe because I have seen more of Lost Odyssey. But it looks Epic and Fantastic....Those in game screen shots look spectacular...and I downloaded the 10 minute video demo/walkthrough at TGS on my xbox 360....the battle system looks incredibly fun. I can't wait for this game. WOW.
Blue Dragon on disc 1 had quite a few CGI cutscenes but I love it however I must have had around 14hrs of gameplay out of the first disc! Am on disc 3 and i think its a 1 layer dvd as the drive is much queiter.
4 discs for Lost Odessy? Meh doesnt bother me because the 360 has all the top quality games.
