I don’t want to jump into the future so quickly but let’s assume the thread doesn’t need to be time ordered 
I made some game (position) “editors” more so than games since I didn’t code the game logic fully.
One used for Random Gaps + Pie Rule - #249 by shinuito
and one for a game called tumbleweed Tumbleweed: this game weirdly reminds me of Go - #28 by bugcat
Mentioning the above in case others @Vsotvep @le_4TC @RubyMineshaft etc wanted to mention their tools they’ve made for some forum games 
I can’t really remember if I’ve made many proper games, probably done bits and pieces for a gamejam the odd time or followed some tutorials to make rts type games but never to completion really.
I can delete if it doesn’t count for this thread (also only coding as an adult because I never learned or knew how to as a kid)
