I would ask for proof on that. Wargus 2 works for 'some' people, but for me it doessn't and there are two very full threads of people trying to follow simple instructions that still don't work.

Starcraft is the same as it all comes down to stratogus install directories, certain versions of files that were extracted and put in a number of places. None of which work. And for starcraft there is limited support for the icons and model skins as it isn't a finished product.

Bos wars I thought was pants. Couldn't do much with it as it was just 'odd' to get to grips with.

The only RTS that is close to finished is dune2, although to get it to run smoothly you have to turn off sound. It does however have the full single player game.

I would be interested in that settlers game, really doesn't have the look of an N900 game to me. Seems far to finished and polished.
