Try some HOF games, you can't restart and you can't open worldbuilder.
I can attest to that. Its the ultimate learning tool to be honest. I have yet to win one. This month I blew the Prince BOTM game, UGH!! I practiced too! But with the HoF rules, no reload, no restarts, period, and they can tell from your uploaded saves if you did.
I am making a firm commitment to trying to stop my re-loading re-starting ways. Its not like I do it a lot, 2 or 3 times a game, tops, but thats all it takes sometimes. Reloading and restarting can be very strong learning tools, they help you streamline your techniques and focus your strategies, but it can be a hard habit to break out of.
Just trying some HoF games and some GOTMs, I did discover the HoF MOD, which is really really strong, especially for people like me who like a lot of cities. Pre warnings about border pops, health and happiness caps being exceeded, etc, are invaluable. They are especially strong in the early game, when you want to hook up that 2nd ring resource ASAP, but forget to check to see if the border popped a couple turns or something. I cant play without it anymore, I lose track pretty fast.
Oh, before I forget, I asked rolo to make us another game. I sort of know how, but if I do it, I will have pre-knowledge of the map, and I want to play these as clean as possible. Here is what I requested (just sent the PM)
Kublai Khan, Pangaea, NO WILLEM! (only AI restriction I requested, I figured we are all sick of seeing that guy, he even showed up in our SG game!)
Will do the same as the last one, he will link me to his upload site, I will grab the save, and post the start in the new thread. Expect it in the next couple days. In the meantime, remember, there are other common-game themed series out there, like rolo's LHC. He has those set up the same way, you pick your level and speed, and play in your favorite MOD.
