I gave it a try quite a few years ago. I had a mixed feeling. On one hand, it is a great simulation of actual hardware/firmware dev jobs. On another hand I wasn't sure who the target audience was. If you're doing this for a living you probably don't want to do that as part of a game too, and if you aren't, you probably will find it too dry and detailed because it is THAT close to a real job...
I haven't gotten TIS-100 however many years it came out for the same reason. When I feel nostalgic I just dust off some old tools and do some fun stuff with C or Assembly.
Turing Complete is definitely more of a game, however with a lot of educational value.
Shenzhen has some restrictions and mechanics I don't like.
- circuit board is too small and jumper wires are only vertical.
- assembly lines per chip is too limited.
- I don't like the plus/minus mechanic for conditions.
- not enough microcontroller varients. I often wanted a microcontroller with 3 simple IO pins instead of the XBus pins.
