Many pixel games today take it further by adding shaders, lighting, semi-transparency, HDR, particle effects, etc. so a lot of them share this hybrid old-new look. It's charming if a) done tastefully and b) the animation/art is solid e.g. Towerfall Ascension.
There are a few games that really nail the pixel art, but they are the exception among the flood of poorly done graphics. Those titles usually look different than most other pixel art games and don't fall into the lookalike pattern I mentioned before. I tend to generalize negatively in regards of pixel art because of the vast majority of the bad titles.
