I love this game. It's like Sly Cooper, Jak & Daxter, LEGO Marvel Super Heroes, and Super Mario all got together and had a baby. Open-world 3D platforming levels are like museum exhibits, where you can engage the gameplay/puzzle vignettes in whatever order you please. Well, there is a little bit of gating so that you have to do a few things in order to progress, but I've found that there are alternative paths that bypass the thing that is in front of me. I could also be near the end of the level, just before the boss fight, but I decide to zip back to the beginning to clear some other objectives. I can do that. Checkpoints are fast-travel points. There is a lot of user-friendliness, like not "dying" from falling great heights to the ground. But the vignettes, with their action challenges are as difficult if not more difficult than, say, Mario's 3D World. I would say that there's something for everyone here. The game is modern and fair. Makes it as tough as you want, or just have a leisurely romp.
