I am sure that we are missing some, and I am sure that there are a lot of shmups on the Activision / Atari / Intellivision collections.
Accordingly, please let me know what else I should add to the list. Also, I was not sure about some of the games on the collections listed above; so, if you think we should add some additional games from those collection, please let me know. Finally, please let me know if I should shift some games from the "Traditional" to the "Non-Traditional" lists or vice versa.
