i think that some of us long time fans are more upset cause that is not the first or second time that this game got a new engine. and most of the time got completly reworked in the process. starting from scratch.
if there was just somekind of reasurance that the next time this story gets worked on, it will be worked on for good without anymore restarts. that would help calming the nerves.
thats what i am saying. update take a long time to come out, and when a story gets start over from scratch, much of the first months is put into "worldbuilding" and "character introduktion" and when it seems it finally starts to get somewhere content wise(which can take 6 months to a year)...boom,another engine update.
wether it can be helped or not, it should be understandable why this is kind of frustrating for some people ,since that happened more than once. that why i said, an official message to reassure would be nice. thats all.
