2 or 3 months for a simple demo perhaps ?
You can't make better than Starcraft 2 in 2 or 3 months !
Stop beeing too much like a kid.


And where is the RTS functions, we don't see any unit selection or AI, your ships are dark, your scene is dark and
the sky is too much simple , we see only some planet on background ??

I think you are taking the simple way, space combat RTS :
there are already some bunch of games , even some indie amateur in WIP also lot better than yours.

Space RTS is lot more cheap to make, caus you don't have to make very complex AI for terrain , building , obstacles , no rigging and unit animations etc ...

And because it's space you just need some sky and far away planets : you don't need to make beautifull textures and models, so you spare lot of work.

So your game will be space , so empty in terms of level design.

And it seems you've changed your mind you talk about multiplayer now ??
Will it be some solo campaign or not ?

If you choose Multiplayer only, it's again a big sortcut , that will spare you all AI, Obstacle AI stuff to manage.
And it will avoid you to create a good compeling story , coherent levels and progressive difficulty !

-----------------

So your first title and posts saying i'll make best than any existing RTS was pure cheap talking like lot of kids do !
I don't like people saying too much and showing poor things.
I prefer people just showing something without saying it will be the best , and watching the progress !

So don't compare to Starcraft 2 !


Could you post some clear screenshots of your ships ?
3D model in some modeling program or in MED ?
