TK Has Best Tech Tree in Game

Of course it grants you armies. But even if we ignore this feature, their tech tree allows you to freely pick and choose what you want, without going through an entire line of useless techs (cough, Lizardmen, Dwarves, cough).

There is also no building requirements (ugh) for techs.

Most Techs are unique for different factions. (and even for different LL in some cases.)
But I also wonder, why some of them need buildings.

TK research is a long-go, however, And you can't speed it up (with heroes and/or events like in some other factions.) AND you don't need buildings, but you need cash and/or these urns (I don't know the english word.)

I think some of the tech-trees try to add to the atmosphere of the game.

Vampire (counts) also have a pretty good tech-tree inmho. You have 4 categories, you can choose of from the beginning.

I wouldn't say dwarf-techs are useless, however!

With the lizards, this depends heavily on the buildings, you've built. Only exception is, if you're playing Nacai...

Vampire coast tech tree has even more freedom than TK, and you can actually speed up + researching something doesn't slow down the whole research process.
Empire Tech tree also has more freedom in it. Not as much as VCoast but more than TK.

Agree that VC and Emp have good tech trees too. But Emp's tech tree is so short. By the time you finish it feels like you got less then the other factions.
