can i make war game by unity

Can i make a game of wars by unity ? and these game its levels are the wars which have different times of occurrence like
ancient Egypt and world war 1 and so on ?

thanks in advance

You can make whatever you want.

Look at the FPS tutorials and use that for ideas. Best of luck!

you have to estimate the time it takes to do things like that. divide the different elements of a game into hours and half days of work.
