Of course, you won't be able to do everything you want when it comes to customising the game; there are limited resources in Inquisition's setting, which means you'll have to make choices and prioritise purchases and the like - which is really the most basic way of affecting the game that you're playing. Bioware have also assured fans that their choices in the storyline will cause the sort of lasting ripples seen in the Mass Effect trilogy (minus that original ending of course). Fun though the previous two games were, the stories were slightly lacking. From the E3 trailer it looks like we're going to get a truly epic fantasy adventure, and that players will actually have a chance to change what happens in said adventure. The developers are also working on improving the romance system to be more in line with their sci-fi titles, with courtships suited to each character and situation (which apparently, ahem, climax in "mature and tasteful" sex scenes).
