For one thing, they’re somewhat expensive for little toys: $179. I bet a megacorp making 10 million at a time could do it more cheaply, but Panic seems to be doing it in batches of thousands. A backlit color screen would boost that cost. Then they’d need a bigger battery to provide the same life (~8 hours playtime), which would increase cost and maybe size.
Then yes, while the games would be cooler in some ways, they’d also take more time to develop. One nice thing about Playdate gameplay so far is that it feels very pure: just a few controls and an interesting puzzle. They’ve distilled the fun down to as simple an experience as they can.
I'm sure those developers are getting a cut of that for compensation for their efforts. Wouldn't be surprised if at least $40-50 of that cost is just going to the developers of those games. Assuming there's 24 developers, that means they're only getting between $1-2 per device sold, that's nothing huge.
I also already have the gameplay to one of my video games ported to Playdate (using Lua). Still need to improve graphics, add sound, figure out how to make menus look nice with only 1 color graphics, etc., and I wasn't going to release it until I tested it on an actual device, not just the simulator.
I didn't follow that the project had made so much progress. Damn, it looks insanely cool. A black & white screen is quite limiting for games, though.
Zig looks like a perfect language for such a platform.
