The learning curve is way too slow and the difficulty rises too much with each new game. Lemme explain. Ninja Warrior 1: Very Hard, but learning how to do each obstacle doesn't take that long. Ninja Warrior 2: A little harder, but I can still get to the pipe slider, even in one run. Ninja Warrior 3: It makes Ninja warrior 1 and 2 look like you could beat them EFFORTLESSLY. At the time I reviewed this, I couldn't even get through the ROLLING LOG! Unreal Canine, I understand that the difficulty of the Ninja Warrior games make them fun and keep you wanting to come back and do better than before, but that doesn't mean that each stage has to be extremely difficult at best to do in one run. When Ninja Warrior Ultimate Renewal or whatever you call it comes out, I don't ask for it to be effortless, I mean the difficulty adds replay value and fun. All I ask is that maybe there could be a bit of a faster learning curve. Maybe so we can figure out what to do on each obstacle, if you fail on an obstacle several times in a row, what if it gave an option to have a computer show you how its done, like in Cloudberry Kingdom for the Wii U? All I ask is for a game you can actually take less than 1 week to beat level 1 in, thats all.
