Solid battleground game on mobile
I followed Clash Royale for a long time before downloading it, because I was worried it would be pay-to-win in the worst way like many other versus games out there on the Apple Store.
However, Im happy to report that player skill is by far the determining factor. You can pay to hopefully level up your units early, but you will also encounter opponents whose deck is the perfect counter to yours (so there is risk, and the opportunity to beat paying players). The fact that it is often streamed on Twitch TV and has a small esports following is just icing on the cake.
