I completely agree with you! A launcher app would be perfect, otherwise the whole thing is going to become a weirdly unwieldy collection of single apps. I hope that something like this is planned for the future. The launcher they already have for old Genesis games on Steam is fun…but probably a little processor and GPU-heavy for mobile platforms.
The Genesis and Sega CD were two of my favorite systems way back when. Loved my Dreamcast too.
Thanks very much for reading and for the reply, I appreciate it!
