I love infrastructure games. It took me a long time to figure out that I had to repair the lines twice to actually connect them, even though it was sort of mentioned in the instructions. I thought I had won when I had actually only done the first pass on every line. I never did figure out how to stitch the whole grid together. The load indicators seemed weirdly inconsistent. I couldn't really predict how a given section was going to respond to having a node added to it. Sometimes the new node would completely drain the entire grid and sometimes it would basically not change anything at all and I couldn't really figure out what determined it.
