With the money already spent, I think it should be played. The nagging problem would be that the game, unless an emulated MS-DOS game, is tied by DRM to their launcher.

But still, in the line of not losing as much by not playing something you spent on, playing the game could be good at least to leave an in-depth review about the qualities of the game, the technical sides, the background of the company, price point, etc. And you could also post the review to NeoDB (part of the fediverse), Steam (if you have the game there), GameFAQS, etc.
