Fallen Enchantress already has fixed teams, i.e. permanent alliances.  You set them when you configure the AI opponents.  Unfortunately, those do not share technology trees - they may trade all techs, but that is nowhere as effective. 

Quite a few games in the past have had that feature, but I have never seen a mod add it.  Alpha Centauri and Civ IV(?) had it in the original game.

By the way:

I apologize for my English.  In time, I may find someone who will correct the original post.  Generally, it's about an interesting approach to pre set alliances.  One has the option to start on the same team, and research technologies together.  I have been appreciating these as far back as WarZOne2100 (the free version for the PC).  It's fun to play in an alliance.  Especially when performing time consuming research in the tech tree.

By the way, don't apologize for your English.  It's perfectly understandable.

thanks

I'm not sure that this is civilization 4. I'm only sure about the mod "Fall from Heaven 2." in alpha tsentarve not remember fixed unions

When you configure the AI players before starting the game, you can place some on the same team as yourself.

You can make an alliance in game, but neither of the two allows you to share research.  You can still trade research though - I always trade/buy all of the technology that I can afford.

Yes, diplomacy needs work.  Nations should not try to extort their friends, allies should join their partners when they are attacked, and AIs should be quicker to gang up on Warmongers.

I hope all these would get worked on in Beta 5.

That would be part of the polish phase of the Beta.  To be honest I have never even tried preset teams.

in the mod (Fall from Heaven 2) could even ask to teach technology:

Adding paced his, and AI, we get a big boost. I taught myself to 17 moves. With one ally teach 10. With all the allies, I teach 2 turns. Striking for diplomacy thing! I very much hope that it will be in this game. If the Empire and the Kingdom of different technologies - let there be a chance of such a regime, only a fixed union in the same group (that is, all the allies of the kingdom. Or all allies empire).

here is in Russian:

в том Fall from Heaven 2 можно было даже просить учить технологию. Складывая скорость обучения свою, и ИИ, получаем большой прирост. Сам бы я учил 17 ходов. С 1 союзником учу 10. Со всеми союзниками, я учу 2 хода. Просто потрясающая для дипломатии вещь! Очень надеюсь что она будет в этой игре. Если у империи и королевства разные технологии - пусть будет возможен такой режим, только при фиксированном союзе в одной группе (то есть все союзники королевство. или все союзники империя). вот ещё на русском

Yes. in the original Civilization 4 is such diplomacy. just amazing diplomacy.

большое спасибо.

Wa-huh?

Google translate: "We will improve this area of the game. we may not be able to make it as good as you want to release. We will continue to work to make it better."

Another detail. Can I go through the Outpost ally(team)? Can I go through the city ally(team)? Is the only passage close city or Outpost. Well to make it so that you could go through them.

Еще один нюанс. Можно ли проходить через оутпост союзника по команде? Или через город союзника? Бывает единственный проход закрыт городом или оутпостом. Хорошо бы сделать так, что бы можно было ходить сквозь них.

but in the game it is? that is, when an alliance for example? common "vision area" is very necessary for the team. and there's a need - the ability to pass through the city and Allied Outpost (recently stuck again - only pass through the city ally. bypass - through the floor map must go)

NAP optional extra for an ally in the team. that is, it is already enabled by default. and pop-up message, "We invite you to NAP. pay us" from oyusznika team redundant. actually superfluous and stitching in the diplomacy (in the contract)

There are major improvements? Total explored area of the team? The ability to pass through the city allies? Free treaty with the Allies? Total tech tree (includes \ deactivated)?
