There is no shortage of top down realtime strategy games in the App Store. Some of them offer crazy themes, others try out whacky gameplay, all in the name of cutting through the noise. Today you can forget the gimmicks, because Battle Nations might be the most well rounded of them all.
This is a game that doesn't forget it's purpose: to entertain. Battle Nations borrows and refines a ton of mechanics from its iPhone and iPad RTS predecessors, such as online realtime combat. There's also a non-realtime multiplayer component where you can target specific players. Think Crime Inc. style social combat.
