I've iconed that game, anon. Are some color issues the low, indoor light lit by candles, perhaps? I've found that with candlelit scenes that make the subjects too orange, a color balance layer can help. Usually I'll set the cyan and blue a little high to offset the orange, then lower the opacity of the color balance layer. Sometimes I'll even go way too far with the cyan and blue, then set the color balance layer to screen or soft light, then adjust the layer opacity from there. Another thing I enjoy using is gradient map. I have a small pack of gradients I downloaded from Tumblr ages ago, and I go ahead and set the gradient map adjustment layer to soft light before I start cycling through the gradients to see how each affect the orange in the image.

As for sharpening, I used to be guilty of oversharpening icon when I had a bad monitor. In my experience, less is more. I tend to duplicate the base layer, sharpen that, then lower its opacity. You can also use Edit > Fade Sharpen and bring it down. Whether I'm lowering layer opacity or using Fade Sharpen, I rarely have the number about 30 or 40.
