I'm, of course, excited for all of these! Though especially for the ones that have not been accessible in the past. I'm not sure what your plan is exactly, but have you considered charging money for some of these (at least for MARDEK 1-3) on Steam? People would surely be willing to pay money for that to have it on their Steam accounts purely out of nostalgia, and naturally to play it offline and with whatever enhancements you might be able to add. I would be willing to pay some amount below 5$ for the trilogy, and I imagine many others would as well. Folks are willing to support work that they love(d), and it would be especially understandable in your current situation. I can remember many other flash oldies that released on Steam similarly, and people are generally eager to spend a few bucks. Especially for MARDEK, where the value-for-money ratio is still amazing even if you have to pay a bit.

Anyway, great stuff! Certainly a step in the right direction towards establishing yourself as a creator.
