Today I installed the Remaid of Dreams mod onto my Steam copy of Fata Morgana as a test. I’m pleased to say the process went well and I’m happy with the results as well. You do just have to launch an exe they give you, but they have made the installation very simple and all you have to do is direct it to your game’s folder. Personally I’m going this way because the increase in resolution alone is such a difference; 800x600 is tiny. There are some additional stories for after the main one added maybe, too? But the big epilogue I definitely want to continue to as a club if others are interested remains its own, separate Steam purchase.
The one subjective possible downside is that the artstyle has been slightly reworked in the CGs and backgrounds. I took a few quick screenshots from a Youtube comparison to share, original first and updated versions second:
Make of that what you will. Personally I do have a bit of an attachment to the unique original look, but I don’t think this is nearly as bad as a lot of remake art changes I’ve seen, and it’s definitely worth it for me. Those experiencing Fata Morgana on a platform like the Switch will only know the latter anyway.
