OK, Quest mode is separate...
Story Mode:
Can I have several versions of the same class running around? Like two different experience-leveled thieves in two different save games?
"Delete current party" --> if I have a party that made it through the first few adventures, and then delete that party, is my "progress" through story mode now gone? (Can I reform that party or a slightly different one to continue on the adventures, roughly where I left off?)
As for "rewards" collected. Is that a specific item or something due to quests? Power, Skills, and Deck seem to be pretty much the sum of my characters at the moment... If so, then if you wanted to pick up later in the adventures (if you can), then you wouldn't have access to whatever these "rewards" are?
Thanks for clarification...
