Wat. Een. Expo. Azuma's Sacrifice, Fiddlehead, Thread of Corruption en Synth Protocol. Vier games die de Best Game Award waardig zijn. Uiteindelijk kon er maar één winnen (Azuma). Maar dat de kwaliteit hoog lag was een understatement. Wat een prachtige creatieve prestatie weer van alle teams!

All my websites have 50% Chinese traffic. Which is odd, because they are in Dutch. Who in China knows Dutch? It turns out this is bot traffic, to train AI. So China is doing 50% of all traffic of all my sites to train their AI. This is madness... 🤯

Game Over voor games? Vandaag heeft DGA/VGFN brieven verstuurd naar EZK en de EU. Er komt belangrijke Europese regelgeving aan die het maken en spelen van games gaat reguleren. De vraag is: positief of destructief? Wij vinden dat ouders, kinderen (gamers!) en spelmakers betrokken moeten worden.

Got this fan release today. The game Illusion City for the MSX Turbo-R. One of the very few games for that system. Made by legendary developer Microcabin. Now fully translated! Boxes and put on a cartridge by Outer Heaven. Loving it 🤩 #msx #msxturbor #fanrelease

Back in high school, all my friends were playing OSM during IT class. @jeroenderwort.nl started in a similar way my brother and I did. He grew his startup from his attic to 100M+ users. Beyond our shared love for games, it’s inspiring he also wrote a book about it. Check out his book: Scoren!

The past few months, I have been playing Online Soccer Manager again. It's still a lot of fun! A lot of popups need to be closed per session though. It could definitely use some polish... Popularity is declining it seems. Had a group of students that didn't know about it. That's not a good sign 🫢

WhatsApp now has a huge AI button always on screen. 😱 This is too much imho. I'm all for clever and innovative use of this tech, but you CAN overdo it. An app like WhatsApp benefited over the years of its predictive was and simplicity. Seems META is abandoning that strategy now.

Penguin Panic is most popular in Vietnam! No idea why. Maybe Vietnamese are particularly fond of penguins? As one of the people reviewing it says: "This game is really fun! Definitely worth playing. I’m giving it 5 stars and recommend it to everyone." Couldn't agree more... 🐧🇻🇳
