That said, I have to break down and whine just a little bit about my suspicion that a lot of the economy tweaking that follows from the "more money" theme is not balanced yet for large-map players.
Basically, it looks like it will be a real hat trick to figure out how to manage your sluggish economy on Gigantic and Immense maps until you encounter enough other civs to start earning this Disney money. Add that to the Thalan's new-found responsible attitude twoards population growth, and, well, I'm likely to play my next couple of beta games at a lower than usual difficulty.
Their population penalty is effectively only 20% (they start with Xeno Medicine) and later is negated entirely by their two unique Pop Growth techs.
I dunno, I didn't have any trouble remaining the top economic player for basically the entire game. Granted, I placed my Hyperion Matrix on a 300% research tile, bought the other two buildings, and set the slider to 100% research and RUSHED to Galactic Stock Exchanges and the second Government tech.
Picked up shields and stingers, and the first of both the Thalan's research and industry buildings, then I actually started expanding like any other game. Was probably about December of the first year before I actually started expanding. I used my research capability advantage to remain the top in military, influence (well... that was probably just the Stock Exchanges...), etc as well. I also made sure to pick up Economic and Research Treaty from every Major race as soon as I met them.
This was on an Immense Galaxy with 9 random, tough opponents (no minors). Still haven't finished it (not suprisingly), but I am very, very close to a Diplomatic Victory, and could easily just finish the game with a Tech Victory if I wanted to.
