What a terrible comparison, Rumbler.
Most side scrollers are low budget and the nes graphics are a necessity. More than that, no one here is talking
about just graphics and UI, but also gameplay systems, improvements and refinements over gameplay, what's new, evolution to the genre, things like that. Many modern 2d platformers (shovel knight, kero blaster, freedom planet) feature things you could never do on an nes or 16 bit platformer. And when they are tributes, they also feature completely different and in many cases improved gameplay systems. On the contrary, I didn't see one single thing you can't do in BG in that gameplay demo. Meanwhile, Mighty Number 9 is an ode to mega man, and is an honest to goodness new take on the franchise , combining the best of classic MM and MMX while still having its own identity. What's Pillars of Eternity's identity? Because I'm not seeing one from that demo.
