Warfare Inc, then Command and Conquer. Red Conqest and Robocalypse are decent as well, but Warfare Inc is the best. Warfare Inc is the only iPhone RTS that really captivated me and made me feel addicted. It's very polished and fun. C&C definitely has the best graphics, though.
Ok I love warfre Inc too but the biggest thing that prevents it from being the eat RTS is the bug where units do NOT attack while moving and the lack of a zoom. Haven't played command and conquer but I remember people saying that it was too easy red conquest has none of these problems, has a dedicate skirmish mode with 15 different maps for different sizes, 4 challenge types with 16 total challenge missions, and a short but very dedicated campaign which is divided in parts for free downloads. In my opinion een without the online multiplayer (which is coming in a month) it's still the BEST RTS for the iPhone.
Mechcraft, hands down Mechcraft is the best hands down. The independent developer is also promising spinoffs such as Dota and nexus wars compilations. Right now, there is Mechcraft, which is pure RTS and Bots & Trons, which is a smash tv like RTS. Fans of Starcraft will like the pure form on a handheld.
Mine is red conquest for sure. Weirdly there are no votes for Land Air Sea Warfare. I havent played it but usually it gets a lot of votes in topics like these.
Yep, nothing matches up to RC, even over two years later. Sadly, there's only a handful, literally, of "good" RTS games on the iOS even now. But yeah, Red Conquest is so perfectly suited for the platform and offers great unit micromanagement. Pretty much every other RTS feels like a watered-down PC RTS: Starfront, Red Alert, The Settlers, LASW, Warfare Inc. Was amazing playing RC online during its peak days. Crazy 4v4 matches. Miss them.
