Sure. I have, too. And, I've played far more expansive ones, and had fun with them, too. You can make your own fun with even the sketchiest game, but a good game can handle quite a lot of material before it collapses from its own weight. 5e, happily, has the potential to cater to both extremes, from using the basic pdf, alone, to PH w/o optional rules, to pulling in DMG modules & the like selectively, to allowing everything WotC so much as tosses off in a UA, to anything-goes.I don't understand all the clamor for more options, more rules, more classes, more crunch. I've played far more limited RPGs and had fun with them for years.
OK, those last two may become a tad reckless as options expand. In hearkening back to the classic game, 5e has opened itself up to some classic issues, too. But it's just a matter of being a bit selective about what you allow. There's always going to be 'basic only' or 'Core only' as conservative, unchanging (but for the rare errata) options.
