does someone has a good tutorial or example of how to make a tile based game.
(rts kinda way like red alert).
As other posters suggested, start with a simple 2D array for your terrain and show a character moving about in a 'roguelike' style.
I would forget the 'rts' portion for now. Creating the interface, drawing the graphics, and moving the camera about is a much more complicated task and even if you know what you're doing, it will likely take months to create something that even rudimentary (think boxes and rectangles instead of any graphics) resembles a RTS.
