As the title suggests, I just got my iPad in the last month and have been looking for an awesome RTS game. I played a lot of Starcraft, command and conquer, and Warcraft 3 so anything close or similar to those games would be awesome. Idk if this is the place to post this, if not sry :/
General discussion is the right place! You might want to try Land Air Sea Warfare for an awesome, feature rich RTS. No multiplayer, but the game is otherwise excellent. Also check out gameloft's Starfront Collision for some multiplayer, different races and campaign. It's a Starcraft clone, but the unit limit (only 40 or so compared to LASW's 1000) is extremely irritating. Finally, there's a new Mech RTS that just released, don't remember the name but you can find its thread in the iPad Games section.
+1 for "autumn dynasty" you may want to take a look also at "total war battles" (streamlined RTS) btw. haven't got "brainsss"... trying out asap
Warfare Inc has hundreds if not more user created levels. Its Iphone only and graphics are functional but not pretty. However its the best RTS on IOS by far. Why? Well its well made, FREE (no IAP either), has a large user base and prints real money when you win. Ok maybe not the last one but its definately worth a look if RTS is your thing.
