You mean ... like having standard game for 1-12 ... where plot will be resolved and finished.
And DLC as separate story, lets say ... happening some time later, not directly related to main game plot, but coming out of it ... where you start at level 12 and go to 20?
Maybe even possible to play as its own game, without need of basic game?
Like ... Origins and Awakening? O_o
Yep, that was the sort of model I was thinking of. Or even (again like DA:O) a bit of a mix of shorter DLC adventures that maybe only give you an extra level or so, with one or more bigger Awakening (or ToB) type expansions, most particularly to provide a big finale. Or, yes, there could be another game to take us to level 20 that lets us import our BG3 character but doesn’t actually require BG3. I can see pros and cons to both approaches.
I do feel that a story that takes our characters all the way from levels 1 to 20 should give the feel of years passing, and be the tale pretty much of a life. This can be done in a single game (DA2 did a reasonable job of it, given its rushed development) but I don’t get the sense BG3 is being set up in that way.
