2) Trade screen is confusing: I miss a clear explanation about who is giving what. I only found out which offer is whoms after a trade partner offered something that was not in my list.
I understand the confusion, it has thrown me a few times, but just remember left are your offers and right are theirs.
3) The tech tree is a mystery to me. I'm missing a graphical overview, right now I'm only selecting technologies that somehow sound beneficial. What I'd like to see is a graphical depiction of that tree to make well founded decisions.
It gets easier as you become familiar with the game but they need to offer a downloadable tree that can be studied,
4) Fleet management: I have a fleet of three ships sharing a tile with a single ship. I haven't found a way to combine these. Is there any?
