I found these posts really interesting in the past couple of days:
Can 5E Play Like an Old School Game? - well, can it? John Arendt ran a big open hexcrawl-style adventure with 5e and muses on how it can be (or is) more old-school like.
Tim Shorts is looking at larger combats in D&D. Me, I loved Battlesystem. Not great for tens of thousands of troops, but for big PC-centered battles it was fine and fun.
MiniPainter Jen made Goremaw a color I never would, but then again, it's very interesting and it's well beyond any painting I'll ever manage to do.
