Good job, government. Your social media bans just taught the kids espionage skills. This is no different than using classified ads in the newspaper to share coded messages.

It doesn’t always seem real to me, but here’s the story about I, the son of a boatbuilder from a small town in the North of England, became the lead designer on AvP 2010. I was 27. (I guess this is another “Aliens is 40” thing)

I haven't had any outright problems with this at my current job, but still had to get an approval and theoretically they could block me from my side projects. Have also talked with some other companies that said outright they wouldn't allow it. Fuck that shit.

if you want a fun way to stick it to tech giants and gen AI today, get the indie game where they literally made all their sprites and animations with embroidery, and leave a review to support them, because this is SO. FUCKING. COOL!

Being a solo dev with a background in mainly programming really makes me realize what parts of game development I'm less good at. In my case: UI Hats off to all you UI/UX designers out there. Keep making cool stuff, and maybe I'll manage to learn some decent UI design one day as well! #indiedev

When I played Gravity Slugger last week healing felt too weak, so I added two new upgrades: Armor (reduces damage taken) and Life Steal (heal on hitting enemy) Played again yesterday... made them WAY too strong. Never survived that long before. Rebalancing time then, I guess 😅 #gamedev #indiegame
A screenshot of two game icons. One is a futuristic shield with a big yellow plus sign and the text "Armor", the other is a heart with a smiling mouth and two pointy teeth with a blood drop hanging from one of the teeth and the text "Life Steal". Both icons have green backgrounds.

Me + trains = cursed today. On the way to a music rehearsal, I managed to miss three trains for three different reasons. Now on the way back, there's apparently an evacuation alarm at the station where I have to switch back to metro so the train I was on couldn't stop there.

Me: I'm a game developer. Is any post related to my game considered self promotion?
Mod: Of course.
Me: Okay. So given the 10% rule, would i need to post about someone else's game at least 10% to be allowed to post about my own game once?
