I can't comment on Divinity 3, but regarding Flames of Vengeance, it's actually quite extensive for an add-on and to just call it a patch would be doing disservice to the amount of work that's been put in.
i diden't meant it to sound like it's an update patch on.
i tryed to give the frame picture, that it's gona run on the same graphics, and with some changes, would still be the same gameplay, on the same story ongo.
the idea to my question was, what graphic/gameplay/storyline, and details, would you hope for in the next game to come, not the expansion-because the expansion features are somewhat obvious.
so any way, sorry to diss =) have a happy moderating/playing
