Evan, forgive me if I should not give detailed feedback here on your replays, but wanted to give you some insight on your first game on the 30th on the map gen:
First and foremost, I think the biggest thing I noticed was that your opponent (Cascade) kept his ACU in base longer, utilizing the build power to get factories up and running. Your raids were good, but they did not do enough damage to cause him to stall on mass nor energy, allowing him to get more units up. At the 2:50 mark of the game:
As stated, your raids were good and took out a good amount of his engineers, but if you zoom out and do a reclaim view (ctrl+shift default, if you did not know) you can see there is 4k+ reclaim on the map in large concentrations. His lone, surviving engineer provided enough income to keep operations smooth. With this, he has 2 land factories + air up while you are working on your 3rd land factory:
On that note, you did not send an engineer to the corner where there is - what appears to be - 5+ factories (~200 each) worth of reclaim or 25+ tanks .
At around 6-7 minutes in your ACU and his have exchanged fire to the point where his has ~3k hp and yours has ~4.6k hp: ALWAYS bully a Cybran ACU, especially as Sera/UEF where you have a big hp advantage. I personally would have sent my army to that side to put pressure on him and possibly end the game there and then.
In addition, you never got any air presence as he kept 1 t1 bomber attacking your air fact, destroying the unit in production. A bit after he sends 2 more bombers and they get dozens of passes without any interruption: keep at least 1 t1 maa back in your base without moving it to prevent this as it certainly was a huge factor in costing the game:
Around 10 mins (not much game after this) you can see that after a major fight Cascade "won the reclaim field" and was able to simply overwhelm you:
So, main lesson for this game in my opinion:
GET THAT RECLAIM
It does not matter if the map is 5x5, 10x10, 15x15, 20x20, etc; the player(s) whom get more reclaim tend to WIN the games. Going forward, especially on map gen, zoom out while teleporting in, and hold ctrl+shift so you can pre-plan how you will go about playing the map.
Hope this helps and adds to your success! If you want me to remove this post let me know.
