Battle Supremacy seems like a better choice if you have a newer device and a controller. On a Mini 2, graphics don't look as good as the trailer/screenshots, plus there are some framerate issues. The controls for the tank and drone forms feel too loose IMO. The jet controls are pretty good though
On the flip side, the maps are impressively large and seamlessly switching vehicle forms is very cool
It's strange but I kind of had the opposite reaction to the controls. The tanks and drones control pretty well. I like that the "tanks" are a little speedier than those in the first Battle Supremacy (which, of course, tanks are supposed to be slow so that's just me enjoying the faster movement).
I don't really like the flight controls for the jets. May just take some getting used to, but I prefer movement on the left side. Kinda wish they had the option to flip the controls. Am actually favoring accelemeter for now. Really wish there were just more control options period. It seems like Atypical streamlines the control options with each new release. Their older games actually had more options.
That said, I'm liking it from what I've played. Seems to have a lot of content, although I don't know how varied the missions will turn out to be.
There are some framerate dips -- most noticeable when there are close explosions. But it isn't enough to ruin the experience for me at least. Graphics I would say are on par with the first Battle Supremacy on a Mini 2.
