Yeah as someone else mentioned, it would have been a better idea to release some of the "real" games instead of the hacks. Maybe a "SPORTS" section with Bowling, Realsports Tennis, Football and Soccer, Basketball and if possible Pete Rose Baseball
As far as what I think is unplayable. I think that's been covered too and for me it's the same: Yar's Return, Space Duel, Lunar Lander and Caverns Of Mars (the last two are a real shame because they're very playable aside from the seizure inducing playfield flicker.
I know you guys have covered all of this months ago but I just had to vent
In retrospect, MOST of the games are nice but as a software QA nerd by trade, the ones that stink really stand out and piss me off
