is it possible to play through the entire game with only 1 character? you basically kill of one of the character at the start and then continue onwards alone, if so, has anyone tried it?
It seems quite possible. I'm currently Lone Wolf'ing on Hard Mode with a RoguexRanger, and the only truly difficult battle that I've fought is versus King Boreas'- which is borderline impossible because of his infinitely spawning minions. That would probably be the only thing that would stand in the way of a solo playthrough.
i would think so as well, i cant remember anywhere you actually need to have more than 1 player, other than some sidequests. the beginning would be pretty difficult but should be possible, might have to try it out
