I agree. They should fix BW (its situation in unacceptable) and plan for a sequelPeople were not at all universally receptive and accepting of Stellaris's 2.0 changes, and in fact I flipped a lot of my reviews to negative. I haven't even purchased the Apocalypse DLC, nor do I intend to.
Sequels should be released as sequels. They should not be papered over the original game.
I think it's obvious Tyranny needed more time in the oven but Paradox doesn't spend too much money on games, it's just part of their philosophy. You can't do that with a new IP CRPG though, it will show in the final result.
I doubt it will get a sequel. Who cares though, we are living in a new golden age of CRPGs.
