Keep in mind that i'm not a first timer, i have a lot of experience with construct-ish programs like mmf and gamefactory.
And yeah, i'm struggling with making my little soldiers move along a grid...that seems to be the hardest part for now.
Hey, well if you have the drive to tackle it, then by all means go for it. An isometric RTS game would be hawt. I've had experience with iso games before, so if you need any tips then feel free to fire away. Personally I never bothered with a grid, I just used 8 way movement or ball movement... the animations are the key to making cool tile transitions IMO.
Good luck my friend! Hard job, but not impossible!
