What ideas do you guys have? This is for my ODF game. I've been thinking about this for some time, and the two real methods I can think of are:
-Different colours on the textures for units.
-A coloured icon at their base (maybe a disk on the ground beneath them).
I've been experimenting with colours for a couple of hours, and all results look crap. I have a very specific look to my game with the desert theme, so unlike RTS where vehicles are made to look generic and suit lots of landscapes, mine have desert camo. Desert camo with a splash of pink on it look rubbish.
Anyone got any other funky ideas for distinquishing between units? It'd need to be obvious and just take a glance (without the units being selected) to be able to tell the difference.
