@Caccio, I think there must have been some missed communication somewhere.
when I said a larger dungeon, more monsters etc, I mean in the game itself. Start the game and as you have seen there are more character jobs and races to choose from. This means even on the flaws you've already played you'll be encountering things like goblin shaman and the like that you weren't finding before, and of course, after you go down passed where the demo finished on the eighth floor you'll have another 17 floors to go with lots more monsters and enemies some special bosses.
As for the bazaar, as I said, it's not a major part of the game and won't give your starting characters any advantage.
Basically it's like a super version of the usual shop, where if you have found a particularly good weapon you can put it up for trade, and anyone on that level of the dungeon or higher can buy it, giving you coins in your turn.
it's hard to anything worth putting up and I'm not sure how many people use the service. Really your best off just looking in the dungeon and enjoying the content as a single player game as I said.
