This is the reason that these games are worthless on PC.
Excessive, at times even game breaking, drm that ensures an even earlier end to your ability to play them because we all know steam will outlive the Ubi launcher.
They are boring as fuck, they feel more like a chore list than a game and they all have Denuvo. Not even free I will get any of them. Fun fact, I have quite a few Ubisoft games from freebies here and there and have yet to play any of them.
I actually bought anno 1800 a while back when it was on sale, running it under proton was impossible as the performance was absolutely terrible. It also damaged some system files which took me hours to fix. Pirated copy worked perfectly on lutris though lmao.
