How much RAM is used for game?

["Bryan Parkoff" <nospam@nospam.com>]

    Is it true that all games using high resolution (6 colors) are written 
in assembly language that takes only 32K RAM?  If some games use double high 
resolution (16 colors), will they be still using 32K RAM in one or both 
banks?
    It looks like $2000-$5FFF are being used for page one and page two as 
the animation.  Do you think that 32K RAM is enough for all games?
    If you want to develop 256 colors for 280x192, can it be developed using 
slot 7 controller card?  Do you think that new softswitch will be added from 
$C700 to $C7FF?  It looks like 26,880 bytes (280x192x256) in main bank and 
another 26,880 bytes (28x192x256) in aux bank.
    New games using 256 colors for Apple II may only take 21.75K RAM.  Do 
you think that it is not very worth to write games that ony takes 21.75K RAM 
while others take 32K RAM.  It looks like that it has to depend on 5.25" 
disk for loading / reloading graphic often.
    Please state your opinion.
