The W3C Games Community group is meeting later today (roughly 1 hour from now) to discuss the changes we've been seeing across the gaming landscape (both web and in general). Anyone can register with the W3C and join the call if interested: w3.org/events/meetings/714cf… would love to hear from game devs, editors, engines, portals, platforms, etc. PS: @end3r, Noel Meudec and I co-chair the group

I chatted with @end3r about the recent JS13K gamejam and the fact that AI generated games were spoiling the fun of the competition for many devs, so I typed up a blog post with some thoughts on how the competition could be restructured 📝 tomgreenaway.com/blog/js13p
