Things I Liked
There were some reasonably sexy techswitches in there, and your mechanics are solid as hell. Creep spread wasn't bad either.
Macro Hatch
You could probably have thrown down a macro hatch around the 12 minute mark. You had a decent bit of bank, you wern't saving for anything particular as Hive tech was still a ways off, and all your injects were spot on. If Resources > Production, More Production.
Econ Advantage
Most of that game you spent taking the economic advantage - for example, your response to your opponent taking a third was to expand, rather than any sort of aggression.
When you take an economic advantage over your opponent, you should look for opportunities to trade armies. This is because proportional to economy, your opponents units are worth more than yours - you have a better economy, so you're able to replenish your army easier.
Once you get to high pop/200v200 engagements, this advantage fades quickly.
Immobility of Mech
Mech suffers from deathball syndrome - a mech army sticks together, or it dies. Because each element of mech relies so heavily on the others (Hellions and tanks need Thors protection from air, Thors and Tanks need Hellions to protect from lings, etc) your opponent is unable to divide his army.
So put your opponent in a position where he has to do the one thing he can't do.
There was a decent bit of harassment in the late-late game, with roaches hitting your opponent's outlying expo's, but this could have happened a *lot* earlier.
Zerg has a huge mobility advantage over mech, which you didn't really utilise. This flows nicely on to my final point:
Immobility of Brood Lords
The moment you tech'ed to Broods, you lost your mobility advantage, and it forced you to engage your opponent head on or risk a base trade. This is a decent position to be in the lategame, but the entire game leading up to that you should have been taking advantage of your mobility.
Overall
IMO, you played this match far too passively. Yes, your opponent let you sit back and macro up a storm, but that doesn't mean you should let him do the same. Your opponents unit composition gave you the opportunity for aggression and harassment - you didn't necessarily need to try and kill him, but he was able to expand uncontested until the very late stages of the game.
You want your opponent to feel penned into his base. You want him to feel like expanding is an exercise in futility. You want him to feel like you're taking the rest of the map while he sits in his corner making sure his siege tanks are neatly overlapping.
./2c, hope that helps. ggwp
hmmmm, yeah these are all definitely things i could've done better. The reason i applied almost no aggression in the game was that I was rushing broods so i wanted to bank as much gas as possible. I made some roaches and tried to not show him the roach count when he scanned. basically my goal was to prevent him from attacking so i could get up a massive broodlord infestor death army. However, he may have played too greedy and I could've had the option to poke a little more aggressively. i think this is more of a scouting issue, I think maybe i should keep tabs on his army size and positioning with overseers and changelings and stuff so that if he is taking his expansions to greedy I can slam out a bunch of roaches and be ok.
But definitely my goal in the game was basically save all my gas for broods and if he decides to push build tons of roaches with my built up larva and take out the push. While waiting take lots of bases. But yeah like I said I should've scouted more so that I could abuse any potential I had to make securing an expansion for him more difficult.
On the other hand, my passivity with my roaches was moreso that if i attack and he sneaks 8 hellions by (he didn't do any of that in the game which I think was the major contributor to my win) and kills my 3rd and 4th drone lines. However there were some points where he could've done that anyway so I don't know.
With the style i played in that game (fast broodlords), perhaps I should research drops and drop a few lings (don't cost gas) in his main while hitting his third with my roach army. I don't know, i feel like the style I went for encourages passivity which may or may not be a good thing.
