That is an interesting idea, but I feel like it is a tad bit too restrictive, and it might turn out like the ill-fated CC19... no one submitted entries, we had like 2 to judge between at the end
I was thinking more along the lines of CC20, where contestants had to make a game for 3 different categories. It would be interesting to see different programmers' takes on these classic games and how they made the games their own by modifying the original concept.
Maybe people could choose 3 programs to remix before the contest's start instead of having others decide? This would give slightly more leeway as to the program ideas and add to the variation between submissions.
In any case, this was just a quick idea to revive the thread, and it seems to have done that.
