I can see how programmers work with their games, and what I can see where things can hang is: Graphics, Music and Sounds.
Programmers need to understand how things looks and how things can move on a screen.
I can only speak for my self, but I want games that looks "professional" and look like a game that has a drive a la arcade games.
For me is an "look a like Arcade game" always a game I am interested in.
I chose few of them sometimes to my collection. (if my wallet allows me,)
I understand that it is Bug fixing and Music/Sound that lagging behind.
A solution could be that a programmer send his alpha or beta game to another programmer and they both agree what to do with the game.
I know newcoleco is fantastic around Music and Sound, so maybe he could help in many ways.
Also nanochess is a very talented programmer, so maybe he also is willing to help where other programmers get struck.
