Oh, yeah, this game pays out a lot when you complete missions. In fact, that's the best way to make money for your guild. Alternatively, you can sell items you collect when monsters drop them or ones you get from material points (which exist in every maze in the game). EO also has a crafting system, where if you bring certain materials to the shop/atelier, new items become available. I'm a little surprised how much they actually can make, but most of it is stuff the game doesn't even hint at, so it's easy to overlook stuff when you're trying to upgrade weaponry/armor. The only downside is that EO4 and EO Untold make it so that a lot of items are disposable, meaning you have to keep getting more materials for them instead of just being able to buy more.
