Do you mean something similar to how Marvel has built their cinematic universe? Launching the franchise with a charismatic lead character that has a trilogy arc, but also introduce a secondary cast of characters with their own stories to tell and eventually weaving the icons into enemble pieces? Works for other franchises and setting up a blank canvas of a whole new galaxy to play in could offer the potential for using that form of strategy in game franchises. BioWare could be best set up to exploit that form of IP building
I mean like WoW ,but not an mmo.
The base game is a platform where more content is tacked on later. Expansions, like with the Witcher 3 but not limited to just two expansions. You launch andromeda and you play all future mass effect content there. You don't have to pop in a ne disc or open a new app.
