I wish the Stella emulator (or any of them) had a NetPlay feature. We could play some of the head-to-head type games tournament style (brackets, double elimination, regular seasons, etc.). March Madness would take on a new meaning in the 2600 HSC with a Basketball or Double Dunk competition.
I think NetPlay would do wonders for the Atari community. I've never even played some of the two-player only games such as Super Challenge Football or Baseball.
Anyway, that aside, I have updated my unplayed games list and picked the following that seemed interesting to me to try in the HSC.
Most of these I have not played before or very little. That's always one thing I've liked about the HSC is exposure to new games in the huge 2600 library. I will have to update this list with homebrews at some point as well. This will keep us busy.
