We played a bunch of times a few years ago and the sessions were among our most fun, most memorable. The lack of game mechanics made it feel very free-form. The game is still fun and definitely still playable.
This is why I like OSR versions of D&D so much better. I don't think adding 'more' crunch actually does the game any favors. I play 5e only because I must. I know a lot of people complain about the deadliness - but for me the game is just so much faster to play and the focus is where it should be - in the world building rather than the mechanics.
