> it created a text-based record of all objects and their movements on the screen,
Also known as what every single ID Engine / GoldSource / Source[1] / Unreal Engine / many more engines do for records and replays, except they do it in a binary format. It's not exactly a novel idea.
2) Someone who didn't play games in the 1990s, and doesn't like RTS games may very well actually have never played a game with demo recording and playback.
3) Hell, I was unaware that either Source or recent versions of Unreal Engine were capable of demo recording, and I've played the shit out of lots of games that use both engines.
I do hope you continue to refine your demo playback techniques and bring this functionality to ever more complex games! I also hope that game devs will push hard to take some time to add demo recording and playback to most of the games they build in the future. :D
