Be aware that this game is highly addictive and you might loose your job (seriously, but it didn't happen here) or your friends (na, half-joking here). So far I can tell, this game seem to have "no" limits, as you can build ... and build ... and build ... and upgrade ... and upgrade ... and expand your base and so on and so forth. I played it with enemies and found it even better when in free-mode with no enemies to get a feeling of the mechanics "only". Later I ended up expanding my base (in November 2019 mainly) excessively and have a large bot network with over 150k bots, both types together (logistics/construction). The right balance will greatly improve your base production output, so if you have an overflow on iron plate on one side of the base but a shortage on the other side, just build a long convey belt over there to produce up more items. I do this over building short distance conveys and no trains at all. In other words, very long convey belts "pipes" the products/materials around the base on sometimes 15 belts siding on each other. My result: A satisfying production-line build-up game and the soundtrack is just awesome!
