Not to beat a dead horse, but code has to be built from ground up anyways. I just feel it would be a better things for the devs to focus on the broken shit rather than make something new entirely.
The same work has to be done. They’re just choosing not to do it for the existing game.
About $60 a year. How much did the Division cost?
But if you’d prefer, I can also reference Tera. Or Warframe. Both 100% free. Both have had updates that completely shovel out chunks of code just for it to be replaced. Warframe has, twice, been basically rebuilt from scratch because the devs weren’t happy with health/damage models. Then there’s regular introduction of new content.
The only excuse is for them to make money off of it without having to work to fix a mistake. That annoys the shit out of me.
