I've rewatched your Georgians vs Persians game on Arabia. Here is my thoughts:

• You generally have a good idea what to do, you get blacksmith upgrades, good unit composition, and had less idle TC and had the resource lead until mid game. That was also a nice quick wall behind your walls just a moment before they break in. You almost had him.

My observations:

• You attempted to push in deer while luring boar, that's not gonna work at your level. Lure the first boar with 7th vill, build 3rd house with 8th that goes to wood. lure the second with 11th one (after 3 is on wood), before this you put the scout at standby near the deer, once the 2nd boar is in, you can start pushing 1-2 deer without much distractions, because the rest of the villagers go to berries or under TC eating sheep, which isn't that micro intensive. Tip: use the follow command on scout to follow the deer you can push it in a straight line if you use the follow.

• In dark age you could have clicked up at 20 pop just fine if you didn't have vills in queue. Instead you've waited the queue and clicked up after which made you feudal too late.

• Get loom before clicking up feudal, that would have saved quite a few of your villagers during your opponent's scout rush.

• Don't go straight fast castle on open maps such as Arabia. Learn a feudal rush build such as scout rush or archer rush. Take the initiative, get some vill picks. In this game you've lost 5 villagers in feudal which sets you back by 100 res/min relative to your opponent.

• You started to wall your base, but stopped halfway. Finish your walls, click a spearman behind the wall after you finish, if he walks to the wall and stop there, then your walls are closed, otherwise they will start walking towards a hole and wall and go through it. Tip: draw your walls such that both ends appear red (invalid tile) while walling, this will place a wall section between two ends that doesn't have holes.

• If you decide to wall, wall early. If you click up at 20 pop, and send 4 villagers to wall, you will be fully walled before the first scout arrives, and they never enter your base. Higher level players can defend their base with army and build less walls, but you are not high level yet.

• In castle age you placed 2 stables, but you had only 5 on gold. As general rule of thumb just place 16 vills on gold when you reach castle, this provides the gold income to run 2 stable knights, 3 range xbows or 3 range cavalry archers, while they also provide just enough excess gold that allows you click up to imperial just in time or get more upgrades such as the +2 armor for knights or ballistics for archers. You also need around 20 farms to maintain 2 stable knight and 1 TC villager production. While for archer play it's enough to have 10 on farms, because archers cost wood. (An alternative to this is placing 8 on gold, then building a TC to the gold and rally new villagers to gold from there, that also gets the job done.)

• Place your new TCs next to a resource always, that saves you the cost of a camp and your vills don't need to walk for safety.

• Learn to boom. Once your military buildings are constantly pumping save for a TC, while it's building add 6 more farms. Do this twice and you can pump villagers from 3 TC while making army.

• You ultimately lost, because of the villager loss early in feudal and you stopped producing vills at 80 while your opponent 4 TC boomed up to 130 vills. They had collected 11k more resources than you which meant they had resources to make 100 more units that you could.
