This Challenge game has been extremely painful.
I caved on my initial plan to play on deity only. In one of about 30 significant deity attempts, I actually launched my spaceship 3 turns after Liz. I was super weak and had no way to take her capitol. She declared on me ended up nearly wiping me off the map before her spaceship arrived. I hit my limit on losing efforts and had to play a winnable one...
I stepped down to Immortal and was amazed at the difference! Start to finish this was a breeze. I played this on Big and Small, which made teching very easy at the end. Myself, Mansa and Willem owned most of the continent. I didn't get oil, uranium, and bronze, so I went after Willem who had the most space. I used rifles and cannons. It turned out that I wouldn't have gotten Aluminum without Willem's lands either.
Mansa threatened culture, so I had him declare on Wang Kon when he was about 60 turns from cultural victory. This held him up until I could arm myself to take out a soon-to-be legendary city and not lose any cities on the counter-attack.
I finished 1879. This was totally enjoyable, but now it is time to start banging my head against the wall again on deity to attain some serious gratification.
The one thing that I will try to take from this game is to prioritize my GP farm. I found on Deity, I could not get it going quickly enough to get me into the liberalism race. In this current game, I started in a very food rich site and moved my capitol. It is a lot of hammers to give up early, but I hate losing a strong bureaucracy/oxford/wall street city to a GP farm. On deity, my first few cities always go to the land grab and I haven't had a map that worked well to put my GP farm in one of my first two settled cities.
