This game's epilogue is shorter than either of its predecessors. Aside from whomever ends up the divine and the post-epilogue clip we really don't know what the main characters and the inquisition ended up doing. Do we stick around for long? does the inquisition just abandon? what happens to the inquisitor? what of the companions? (this one may be because my first play was a rushed one though, and i'll find out in pre-epilogue/post-corypheus victory dialogues, however even cole whom was more spirit like in my game mentioned he was going to stick around for a while.) We got information on what our warden did (or didn't do if they died), and what hawke did for a time at least, but not our inquisitor. Josephine mentions a lot of nobles want to meet us now but is that all we do? bounce around from place to place meeting nobles until we die of boredom? I'm not expecting all the answers now, as we didn't get a definitive answer on Hawke or the (living) warden until now, but I was expecting more explanation that we got. We didn't die, or wander off, or continue on warden business or become a ruler. We didn't get exiled from a city or become a viscount, and we can still explore the world after the storyline is complete.
It just feels like there wasn't a real ending in the sense that they left it too open, and with a cliff hanger about Solas (and Flemeth technically). yes, a dlc could perhaps resolve that in a way that doesn't feel like a cliffhanger, but we don't know how much or little of a story there is behind that clip. Would I like there to be another game with the inquisitor? yes. it feels like their story isn't as complete as the previous heroes.
am I saying it's likely? No. I've mentioned it as an unlikely possibility and a personal preference.
Would I be content with dlc explaining solas' cliffhanger? probably. maybe. It really depends on how it is done.
but am I content with the ending as it is? No. there are way too many questions left there and if they are indeed planning on moving to another area of the world in future games then it's unlikely we'll get any definitive answers in a future game which is, in part, why I think there should have been more answers now.
