These games greatly benefit from CPU Culling, and there isn't much reason
not to just blanket enable it for all users. There is no case where you'd
want it disabled.
Most games map fine with the default values and I have yet to read a single
complaint on mapping the touch pointer. Going to just leave it up to the users
to setup mapping if the defaults are not correct.
This will avoid effects being unexpectedly broken in these games if the user disables the option globally. This list is by no means comprehensive, these are just the games I could confirm use custom mipmaps.
