Hm yes guess back then games weren't really made with something like color blindness or deafness in mind, a (discrete) hint or alternate solution system would be helpful. On the other hand, its a lot easier today to just look up the answer online anyway, dunno if its worth the development effort, for remakes and remasters at least.

About the realmyst Masterpiece Edition:
The asset quality was very uneven, some looked improved, others looked like straight out of the original realMyst. Its even more obvious with the texture quality, some are relatively high res and others look really blurry. Either one would work together with others in the same quality but mixed like that it really sticks out. It has that "slapped together in Unity" look to me, like some of those Indie games that it was used for.
Also the plants looked terrible, the trees on Myst island look like miniatures and the leafs in channel wood comically big.
Might not be fair to whoever developed it, I bet the budget and/or dev time wasn't all that high for it, but some things, like the lighting/mood changes were probably deliberate, so.. yes, somehow I don't like it.

Everything I've seen from Starry Expense looks gorgeous for example, but of course they're taking their time with it.
