A very addicting game, though, I can't help but notice how some aspects of the game are somewhat similar to Infinity Blade. That's not exactly something bad, but, just pointing out. In my opinion, you earn way too little cash. You have to intentionally not kill the guy for a few more charges to get the most out of the fight. Another flaw is that the Champion is way too easy. I could beat the Champion at generation two with some luck.
Anyways, this game got me hooked, and now I'm at generation 8, with the best horse and lance. And by personal experience, it takes a TON of time to earn the cash to get the higher tier items.
