Is impossible to use a b/w only graphic? why the graphics must use 32 bits colors? The content pipeline convert everything to 32 bit color or something?

If the gameplay area is generally sparse a hashmap of used squares may be even better... Also using colours is 32 bits for essentially 1 bit of storage thats required, if you use bool type then the compiler will optimise... But good thing someone in DoC is making games and not educational software! This is bad, the rendertarget will surely be stored on the video card, why not use a 2D array in memory?
