More than the bugs, I am worried they will repeat their mistakes in a new way. The mount is good, as it was a pain in the ass to move around the map. Though after a simple taste, the mount went away. Looking up the guide, I need to buy it again. Come on, what? Make it a quest reward or something. That mount is a big part of the game's pacing solution.
Second, was Unreal Engine 5 even needed? Does it provide some ease of use so that we get more frequent updates and content? If not, then I would not like stuff to be remade in UE5 again.
The Steam version is fucked, as in, if I opt in to EU5 or opt out of it, the game downloads itself again and again. UE5 content is little and not good, as they had a good foundation with a great population in the UE4 version. Now it feels empty. It is in the desert, but come on.
I hope if people do remake something, they wait and have equal content to the previous version or less before any release. I really hope somehow they just remaster the old version in EU5 instead of making it from scratch.
