My blog Gaming Ballistic is mostly centered around GURPS. But I'm branching out (and have done so in the past), and I'll drop posts that are not GURPS, but potentially interesting, here.
As an example I've written a few about D&D Fifth Edition:
Grappling in D&D5 Basic
The DnD5 Advantaged/Disadvantaged Mechanic
Exploring HP Variations in D&D
Games I'd Like to Play
Monteport 41 - I play D&D5 for the first time
Nosphryc Azurecoat - 5th Level D&D5 Fighter
Monteport Session 42
There might be a few more. But anyway, I will drop one note on non-GURPSy stuff here, for those that are interested, in the future.
