That's fair enough. I misunderstood your first argument.
Why not a 10?
Everything's about the hue-shifting with you. Sometimes I regret telling you about it. It's just another tool, like anti-aliasing for example, and like anti-aliasing it can be overdone or inappropriately used. Sonic Mania is almost overdone, since it has a very noticeable yellow-blue-purple ramp going on. I personally like that look, but that's a personal preference. It doesn't make the art objectively better than something more subtle, and I disagree with you that the lack of it causes the art not to "pop". Terraria's art uses vibrancy, contrast and outlining to make things "pop", and does so effectively IMO. That said, Terraria's art is overall mediocre. Like Minecraft it gets the job done, but it's far from amazing to look at.
Not a 10 because I still need to see how everything related to one another throughout the whole thing, in better non-video quality, lol.
Well, there's a way to use HS less dramatically, that'll still make the colors pop. I've grown to dislike monochrome shading (not monochrome style, like sepia, but just non-HS shading), because it doesn't do anything but add depth, not make the world stand out in any amazing way, lol.
Minecraft and Terraria are programmer art
I'd agree for Terraria, lol.
