I seem to have somehow overlooked the existence of an entire Amazon platform
As had I, yet exist it does, and we just have to live with that. Prime Gaming, as it is known, is trying to tempt adventure gaming aficionados with The Secret of Monkey Island: Special Edition. To wit:
You can find the very special edition in the “Games with Prime” section, which apparently is part of regular Prime. I’m pretty sure I read that they will charge more for the fun sometime in the feature. I don’t know; figure it out yourself, if you really need another version of The Secret of Monkey Island: Special Edition.
