I'll admit it - I've found ideas I wouldn't mind borrowing for my S&W Campaigns.
Notice I'm not saying I'm looking to run a 5e game - I think I'd need to see the full set of releases first, but I do find that I'm not finding what I see offensive to my sense of gaming sensibilities, much as I did see in 4e.
I probably need more time to digest it all.
I suspect it should work fairly well with most OSR adventures, especially the lower to mid level ones with minimal fudging.
Of course, this could be the ramblings of someone under severe sunburn (and careless stupidity)
