those are in no particular order and i included an extra 11 because of my vast experience in gaming :) there are other good ones i didnt include, like Jumpman and some other 8 bit titles and maybe Galactica in the arcade arena and a simple, but addictive arcade space game where you had one little space ship and flew against an AI or another player, the object being to shoot the other guy. it had the option of putting in a sun for gravity effects and doing wrap around screens. oh, and let's not forget Asteroids :)
