How could I lose that?

With less jokes though
- You managed to lock your enemy into a stranglehold! This was pretty much victory assured. However, then:

- You managed to get completely surprised by the existence of Knights, in the sense of trying several attacks on them, all of which resulted in brutal massacres with almost no Knights dying. Some phantoms died in the last great rover/gunship wave attack, but Knights lived.

What to do instead: Badger spam (since you can afford that), or Darts. Lots of darts and a few scorchers.

- The Locust wave went for the absolutely most defended position on the map - the Knight army - rather than for the actual high-value targets, like the totality of enemy eco.

- You spent 9k on Gausses and Stingers. This is exactly how much EcoNoob spent on his trio of striders in the end. Then the striders just walked around the porc.

- Cherry on the cake, EcoNoob only could afford to match your 9k investment by reclaiming the wreckages of your Locusts and his Phantoms right outside of your porc spam - something the porc could also not prevent in any way, being static.

- You did not build missile silo while having the spare income and the territory to place it in a way to cook literally every enemy units. Building 5-6 gauss less and one missile silo with two infernos instead would have probably sealed the game.

- The finale with you losing your scorpion to a stray phantom's decloak and then losing the Krow to the dynamic trio of striders was hilarious but not really that huge compared to above. That said, having the intel on the existence of those striders gave you some time to prepare some actual antiheavies, like facswitch to Widow or a bunch of Ultimata (that Krow could have bought you two Ultis, a spiderfac, and a spy all by itself!)
