I woke up this morning with this idea for a worker placement mechanic ticking around in my head. I haven’t seen it used before, but it might have been used somewhere before. Let me know if you’ve seen something similar; I would be interested in seeing it!
The idea is worker placement, crossed a with a little bit of the movement of Tokaido. Each resource is produced on a track, with spaces to the right producing more resources than spaces to the left. When you place a worker, you can only place it on the leftmost space on the track. So as more workers are placed on track, they benefit from the presence of previous workers. This means you can benefit from opponents placing workers before you.
Other actions might allow you to jump a worker to the next open space. This would leave an empty space on the left of the track, allowing you to gain more resources and stop your opponent from benefiting from your hard work!
Just the seed of an idea for a mechanic, no real game attached yet. That’ll have to come next.
