Shouldn't be a problem. I've never seen a save transfer so you have to start where everyone else does. The Synapsis paints this as a separate story. Even D2 which was an actual story squeal was pretty much self contained.Drejer43 said:
There is a joke in the games about needing to have played the other games to understand the story. There is a character called Asagi from Makai Wars. You can't play Makai Wars because Makai Wars is a future game. You can never play though Asagi's story because the game will never exist to play in the present.
However, you might want to try out one of the games before you buy. It is a niche title, and unless you're into turn based strategy rpg's and their brand of humor it might be money wasted.
100 characters sounds like over kill, but it's something that the PS2 should have been capable of doing. The reason to limit the characters to 10 in the past is more a mechanics issue. Saying they're going up to 100 sounds like challenging someone to 100 piece checkers. Sure it can be done, but what would be the point. More likely they made some kind of mechanics change that makes it practical to do 100 characters at once.
Then again this could be a joke with their weird sense of humor.
