I've just started and found the basic elements to be well worth the trial and error.
Many aesthetic elements tale time to get used to:
windowed screens as opposed to a new window when selecting other options.
I'm going to pull from my mental archive when I found the way a planet can be shunted into full research or money making mode like the Scientist's takeover or Endless party like from the old Ascendancy game.
Combat:
It took time to understand the basics but the mouse-overs helped me know what I was up against. I did notice that when I retreated from combat I lost a non combat transport and was not informed about it.
Research: Since it's limited to 2nd tier level tech, Im ok with how it's laid out for now. I am fond of category labeled tech. Ship, Planet, Economy, Energy and so forth.
Ship Refit:
I haven't explored this yet but is there a way to refit Old ship 1 to New ship 1 and not have to manually refit a ship?
May have a r-click or double click to place the appropriate tech to the appropriate slot.
Have older tech grayed out or have newer tech on top and older tech displayed through a side or pop-up window.
Ship designs have the right feel for the species they are designed for.
I'll keep playing for sure
