Have you guys tried Steve's new android game Nanowars? It's another turn based gem played the same way as Stellar Forces only in this you control a robot which builds other robots. The aim of the game is to control all the nodes and destroy the other controller, or controllers because you can play up to 4 player with the full version.
There's tons of content already including dozens of robot designs to choose from, over 100 maps and regular tweaks and updates.
That's a really good point - with a different skin, it could probably be advanced wars. I really like it, with all the different kinds of robots and loads of different maps.
The only problem in terms of balancing issuses in the game is that ranged attacks are 100% consistent versus melee which has a (approx.) 50/50 chance in a fight against similarly leveled units. Make melee more consistent so that spamming Bombadiers isn't a thing.
