Bought Ridge Racer Unbounded after seeing the Quick Look. It's pretty tedious. It is frustrating in its "well-placed" building facades that nearly ensure, if I am in uncontrolled drift, I will crash. However, it can be all too easy to take and keep first place in the first unlocked car, such that I feel no sense of accomplishment. Perhaps, it's just that I am an unskilled buffoon who can't drift and just keeps pounding on the game until an acceptable outcome is achieved. That said, I have the impression thus far that you don't have to be particularly skilled to do well in Ridge Racer Unbounded.

I'd also note that the textures and color palettes can make it pretty difficult to anticipate and discern the disposition of objects, turns, and the road itself to the degree that the simulation of driving a car is lost and it becomes a matter of pushing your graphics object through a murky tunnel to the finish line.

I kinda like it, I'm not a huge fan of driving games, but I've always had a soft spot for games like Stunts and Trackmania, where a lot of the emphasis was on building your own levels, but yes - Unbounded has issues. The color palette as you mention makes it hard to see where the road is going, and finishing a level feels more like random chance than skill, to a large degree because of the odd way they're handling the destructible environments, as what's solid and what you can drive through isn't easily distinguished.
Maybe more than anything I hope this game does somewhat well so we can get an Unbounded 2 which maybe takes care of these issues, it is absolutely a breath of fresh air for the Ridge Racer franchise after all.
