There's several reasons, and I'm sure others will go into, but I can think of one immediately:
Among other things, at least one has the possibility of being reimagined as something that could possibly recapture what fans loved about the original games and TOR. We ain't never getting another game that allows us to pull down Star Destroyers out of a planet's atmosphere and turning Force-users into Devil May Cry/God of War composites. That flies completely in the face of what Lucasfilm sees the Force as, and Fallen Order has largely filled that slot.
