783516. Completely different conquest strategies for each country. Advantageous for Bluegaria and Violetnam as the attackers, and advantageous for Redosia, Violetnam, and Bluegaria as the defenders. Greenland gets it hard.
If you're playing as Bluegaria on map 254257, you should sign a pact with Violetnam. Conquer all the cities south of you before green gets there, and also take the cities west of you. Help Violetnam kick Redosia out of the mainland, and then send a few tanks to the Redosia capital, and also prepare some tanks to defend yourself from Violetnam. Once Redosia is conquered, Violetnam will attack you, but you can easily kick them out with about 7 tanks. The rest is simple.
As some people have said, capturing a capital doesn't mean that you just conquer their whole kingdom. And even if you capture their kingdom, there should still be rebels trying to get you. Also, it would be nice if we could sign a pact with more than 1 country. Has this been done yet?
945580. The choke point in the middle (Volgograd) is pretty important to win. It's easier to defend yourself and attack the countries on the other side if you control the choke point. Especially if you're playing Bluegaria/Greenland, with a few cities reachable in 1 turn.
342756 as Bluegaria. On my first try, i signed a pact with Redosia, but they got conquered by Purple, resulting in a long, protracted war between me and purple which would never end. So, on my second try, i didn't sign a pact with Redosia, and although they still got conquered by Purple, their armies are weaker, so i prepared tanks on the north and south, and then stormed in. Although i got repelled in the north, and almost did in the south, i managed to get Purple's capital, and then i conquered Red.
31643. Very interesting. Kind of looked like an X. Redosia and Violetnam have a long choke area, perfect for defense. So if you're playing as one of those two, you can sign a pact with Bluegaria or Greenland, and then hold the line until they help you against the other country. Bluegaria has lots of cities in proximity, which will almost guarantee a success against Greenland, which have one choke point, but if you crush it with a tank, they're doomed. Greenland is not recommended for easy gameplay, because they will probably be crushed by Bluegaria within 10 turns. I played as Bluegaria, but it might be more interesting to play as Reds or Violets.
380066 as Bluegaria. Signing a pact with Violetnam is genius! I conquered Green and then it was Bluegaria+Violetnam vs Redosia. Violetnam conquered Redosia, and then i attacked Violetnam and annexed the island at the bottom. Violetnam attacked the island, but i repelled them easily. I conquered the mainland, and then easily conquered Violetnam.
210519 as Bluegaria. Signed a pact with Green, prepared 3 tanks in case they betrayed me, and they did betray me. But i was horribly wrong on my calculations. Purple conquered Red, and nearly took Novosibirsk (my only city that could give me supplies to the south), and together with Green, they took my cities in the South-West. Luckily, i managed to get all 3 of my tanks on land, with the loss of only one tank, and conquered Green. I took Red's former capital, then purple's capital, and won the game.
41534. As Bluegaria.
1. Green near Purple's capital, and Green already conquered the bottom half of the map
2. Purple near Red's capital
3. Me being invaded by Green and red at the same time, and would've conquered me if it weren't for my artilleries and defensive tactics.
4. Two ways to conquer Green. One is blocked, and the other one is empty, and had a tank waiting at the capital.
Strategies: Ignore red attacking me, but put shield so they can't take my cities. Focus on green so that they can't conquer Purple. This may cause you to being 4 hexes away from defeat, but it pays off eventually. Once you conquer Green, purple would conquer red, and then wage war on the southern parts to get their capital.
Map 865358 as Bluegaria. Sign a pact with Greenland. Between their two capitals are basically empty, so if you sign a pact with Greenland, they would leave it empty. Move your troops around so that Greenland can't get a lot of land, but make sure that they're not surrounded by Bluegaria, so that they can help you against Violets once they conquered Reds. Green will betray you, but you can take their kingdom easily.
After that, fight against Violets in the north to take their towns, but then sneak on the south and take their capital, freeing the Reds, and after that, reds would be easily conquered.
That's my strategy as the Blues.
LOL, i named the disease "Madagascar is awesome", and it started in Madagascar. Unfortunately, Madagascar loved the disease so much, he won't let me share it with other countries.

Games just can't be too realistic, it would be a mundane task to hunt down every single army on map to win.
