Valor for Ios and Android is/was pretty much the same thing with a much more boring in game interface(three years ago when I played it) but its 100% on mobile so its a little more convenient. Tribal wars I am pretty sure predates battledawn but I could be wrong and valor was originally a clone of tribal wars. Tribal wars isn't for mobile though. When I played the worlds seemed to take much longer than battledawn. So far I am enjoying battledwaon quite a bit more. Just need to immerse myself into the community a bit more
