The NES was epic for its time, but nowadays those controllers make my hands cramp after minutes. Thank God for the modern big curvy controllers.
Some classics of that time might be of interest to the contemporary gamer, although I think you need to have some kind of historical curiosity for it to be worthwhile. The tools of the times were rudimentary to an extent that hurt what the devs could do even more than the capacity of the consoles imho. I mean, they were flipping bits in assemblers.
The audio though. 8-bit music is fucking stellar. The energy contained, the catchiness, it’s amazing.
As for recommendations: The Guardian Legend is my pick. Cool scifi action-adventure/ shmup hybrid.
