But to do so you either have to make it much harder to play by controller, make it much easier to play by keyboard/mouse, or offer two modes.
I've not played many console RTS's, the ones I have are all PSone titles (distinct lack of such for the PS2/PS3) Every single one of them support the PSone mouse. so there is that option, though it doesn't seem to make much difference in playability, For the C&C titles/Dune 2000 it makes some functions easier but some functions harder.
My suspicion is that the two modes thing would have to be sufficiently different as to require quite a bit of "duplicate" engineering.
Probably. The best of the PSone RTS's in my opinion was Warzone 2100 which was developed as a cross-platform title and performs better on the PSone than the C&C based titles do (uses a 3D engine for one reason) It's UI actually changes depending on what controls you have hooked up to your PSone.
Hook up a PSone mouse and you get more UI buttons. ( but lose the ability to directly drive your command vehicle.
It's a pretty good game, the company released the source to it.
it already seems like making games multiplatform are causing the PC versions to be "dumbed down" a bit.
I've always considered that statement to be somewhat of an "elistist grognard" attitude. I feel the same way to a certain extent. I'm old enough to remember when a larger proportion of PC gamers played games from companies like SSI, and Origin...before DOOM and other games brought in a load of what I used to call "frat boy gamers", but now just call "dudebros" But...without the masses there wouldn't be enough people to make certain genre's profitable. It's a good thing that games are more "user friendly" and don't require tedious note-taking or graph paper maps.
