I didn't watch that video (because it's 11 minutes long), but pretty much the only complains I've heard are 1) online-only, 2) bad pathfinding (which they claim to be working on), and 3) small city size. I mean, I've heard about some other problems with the simulation, but they all seem to stem out of the bad pathfinding (all emergency services responding to the same emergency, all sims in a neighborhood walking to the same job, etc).
