More customization doesn't entirely mean everyone will be different. Usually on a few builds, or setups will come out on top anyway and most others will be ignored. Besides, I have bad memories of some of the NwN builds.. Bard/RDD/PM comes to mind.
Well, there's a few things I'd like to see... 1) The ability to allow chat commands within Foundry, like a player saying something specific causing a trigger to happen. 2) Linking events between foundry modules. So that it's possible to make it so events and choices in other modules can be referenced in a later module…
