We should consider implementing B, or just upping the manufactoryPlaying semantics doesn't change the fact that AI cannot neither use that "feature", nor save GEs for later use. According to VP philosophy that should be either a) removed / nerfed to make AI more competitive b) AI should learn those tricks c) AI should get another bonus to make-up for humans being so smart.
Also engineers really benefit tradition more than other trees
We can try this, but just keep in mind that your first engineer potentially is worth the Oracle, we need to make a single tile worth an entire social policy without making it super snowbally. It should probably buff future engineers in my opinion, and I think it should get a really fat bonus at a tech such as industrialization. another option would be just giving something like +5 or 10% production in the city, this lets it scale much better.And to be clear - I’d rather boost manufacturies, so they would be competetive to popping GEs.
