I've been playing UFO 50 with NES controllers, and CRT filter high, it's been a blast.
I've played the multi-player games with my kids, they love them.
Also my kids have been playing the single player games by themselves, it's amazing to watch them play games like the ones I grew up with.
I really likes "Between two ferns" with Zach Galifianakis.
They even got to interview Obama.
