Actually, I'm a bit curious about production capabilities. While it is true that Zerg can quickly take the natural expansion and instantly boost its production, I have to wonder if now being able to start production of two units every 10 seconds (or four units, if there is constant queen usage at both Hatches) is actually superior to the other races. In tier 1, Terran's maximum production on one base is 1 SCV, 2 Marines, 2 Marauders (7 supply/cycle) (and a Depot); Protoss are just barely incapable of supporting four Warp Gates, including Pylons (8 supply/cycle). So ignoring that this math is completely impractical to actual gameplay, let's run comparison:
Terran (1 base 3rax):
In 3315 seconds,
195 SCVs (9750 Minerals, 195 supply)
255 Marines (12750 Minerals, 255 supply)
195 Marauders (19500 Minerals, 4875 Gas, 390 supply)
Total: 42000 Minerals, 4875 Gas, 840 supply
In one minute:
760 Minerals, 88 Gas, 15 supply
Protoss (1 base 4gate):
In 646 seconds:
38 Probes (1900 Minerals, 38 supply)
34 Zealots (3400 Minerals, 68 supply)
34 Stalkers (4250 Minerals, 1700 Gas, 68 supply)
17 Sentries (850 Minerals, 1700 Gas, 17 supply)
Total:
10400 Minerals, 3400 Gas, 191 supply
In one minute:
966 Minerals, 316 Gas, 18 supply
Zerg (2 base Roach/Hydra):
In 2040 seconds:
136 Drones (6800 Minerals, 136 supply)
120 Overlords (omitted non-larvae costs due to equaling Pylon/Depot)
255 Roaches (19125 Minerals, 6375 Gas, 510 supply)
136 Hydralisks (13600 Minerals, 6800 Gas, 272 supply)
Total:
39525 Minerals, 13175 Gas, 918 supply
In one minute:
1163 Minerals, 388 Gas, 27 supply
...so Zerg's production capability seems to indeed only come out just under twice as ahead as Terran, and 1.5 times ahead against Protoss, if fully saturated on 2 bases compared to full saturation 1 base plays. Note that this would imply they fall behind if on equal bases... Anyway, Zerg's larva spawn mechanic seems to be both a boon and a hindrance, in various aspects.
