I've always fancied japanese style pixel art. I still remember playing megaman x and it hasn't aged a bit. Or even simpler ones like super mario world or the last few pixel based pokemon games.

I remember looking for tutorials for this style, but ended up copying sprites and trying to understand why they such and such decisions. Interestingly enough, I find it harder to recreate pokemon style sprites because they're so abstract and yet a single pixel can make or break it. I know this is a bit off topic, but would love to know if there are any resources for this.
