hotdeck said:Thanks for you guys' advice and encouragement. To make things short, I think my problem is that I don't exactly know what are good decisions for a specific situation, e.g. what building or unit to build in the next turn, if I should accept a proposal from AI? etc. I guess the only way to improve is to play more games and gain experience? I also can't balance things very well. For example, in one game, I was trying for the space race and I only focused on technology leading to Rocketry, but then I have the lowest score of the 7 civilizations and rather weak military units. It seems so hard for me to have the highest score on Noble level. It is frustrating at times, but at least I learned something from each game.
TCGTRF, do you mind sharing your 'cheat sheet'? It will be extremely helpful for my situation.
1) Don't worry too much about your score. All that matters is that you win. On my cultural victories I'm usually last in score. But I won the game.

2) Step down from Noble. By the way, have you run the tutorial? Even though I've played 1000's of hours of every civ game from the first, I still ran through the tutorial and Sid helped me get used to the various concepts of the game. Then I played one game on the easiest level, Settler. I moved up one level my next game and still easily beat it. So up to Noble it was and I've played that for many, many games. I've now just moved up to Prince level.
3) Only 30 hours?


4) As for trying to Space Race, I think for me it's only been because it was the easiest route to victory that late in the game. Space race isn't something you need to plan for from the beginning like a cultural victory. Typically I do a SR because things didn't quite go right for a conquest or domination or as a side project while trying to get a diplomatic.
Good luck and happy civvin'!
