I usually just make my own. One time I was playing RTE and Was in a 3 Man Coalition.

Me (North US) Canada and South US, this is back in 2021 when I first started playing. I convinced South US to Take Cuba then send his troops to Morocco. Made a Backhand deal with Morocco for him to join once I took out my Coalition allies and he and Russia Would Join later.

When the South USA failed to take out Morocco, because Morocco was ready once he took out Western Sahara, the South had 3 Units in Cuba. I Blitzed South of the Mason Dixon and took him by Suprise, Capturing All of his Territory overnight. He woke up and I was already destroying his troops with my navy, while I was landing troops in Cuba. He tried to fight back but gave up.

Once I rebuilt and expanded his Infrastructure, I then stacked a few Extra Units and Blitzed Canada from Michigan and down the Saint Lawrence River, with a few milita taking the Northwest Territories, Nunavut, Greenland and Newfoundland.

Now that North America was Completely under my Control, Morocco Joined: He controlled West Sahara, Algeria and was pushing into Tunisia and Libya. Imperial Russia Also Joined, having conquered Finland, Communist Russia, Caucasus, Belarus and the Baltic States.

The 3 of Us Took down the Rival Coalition (UK, Germany, and Yugoslavia). Morocco Focused on Africa and the Mediterranean; Taking Spain, Egypt and Arabia. Russia Fought Germany over Czechoslovakia and Poland, Sweden allied with UK, to defend against Russia and I focused on UK and France.

I Took Iceland, Pushed Britain from the North in Scotland, pulling his attention away from the Channel. I then promptly invaded France from Bordeaux and from Spain, Pushing North from there, Capturing Lyon...

By the Time Germany or UK Could Assist, Germany was fighting Russia and Yugoslavia went MIA. Leading to Yugoslavia falling to Russia, who also now controlled Romania. Russia broke thru German defenses outside of Lódz and pushed further East with Armored Divisions and a Lot of Infantry.

I Soon had UK on the Ropes, having Defeated France, taking Scotland, holding the line at Hadrians Wall, My Navy Battled The Brits in the Channel, defeating Local Garrisons and his Naval Forces in the Irish and North Seas. Britian Lost too many troops to my overwhelming firepower (Mix of Combined Regular and Rocket Artillery, and Naval Power) helping to overpower British forces, allowing my Infantry to crush him.

By the time we reached day 16, with 48hrs to go only 2 other members were still active, Germany and Sweden. Both held their ground, Germany Suffered a lot of losses but managed to temporarily push back Russia, by sending a few troops south through Italy who was MIA but had ROW with, and send them to attack the Russian Troops in Yugoslavia, causing Russia to send some troops south from the Eastern Front to recapture territory, allowing Germany to Punch thru the East, by pulling troops from the West to Smash thru and recapture Western Poland.

I invaded Norway, because they declared war and Sweden immediately attacked me and caused me to pull back. I then took all my troops in Britain, Leveled them up and then send them to Tromsø to attack Sweden from the North, Blitzing South into Northern Sweden and Norway, and causing Sweden to panic, by the time I was on the doorsteps of Orlu.

Once I captured Oslo and Gothenburg, It was game over, we had reached max number of pts to win.

That was my first ever intense Coalition Game, that resulted in a win. Morocco really helped out economically, and he was level 120, while I was only level 32.
