Tower tactics.

I wouldn't say that it's easier to build Giants than to build creatures from a Barbarian Castle (this refers to the "Impossible" difficulty level)...

And how many resources are needed for the creatures? Remind me... For Giants, I think it's 5 wood, 5 ore, 10 gems, and 5 Bracadia coins.:smile02:

Separately or the entire chain with the necessary buildings?

If you consider the chain, then Creatures are easier. Giants require buildings for all other units. However, they are built on the 7th day of the second week, which means that all the other Tower creatures will also start to increase in number – isn't that a plus!
I actually prefer to play on "Expert" rather than "Impossible". The difference is only in the first month (or even less), because the AI's intelligence seems to be the same as on Expert. But the ease in the first few days is very annoying.:smile13:
