Well ... Most of this has been done on speed servers. I have played a few snails but I've never grown as big as I did on speed. So I might be biased. I'll edit the OP and make sure I say this is specific for speed.
I would imagine this is hard for snail players. Yeah.. Now that i think about it lol
There's been people with 30+ villages on all the regular servers I've played on since coming out of retirement 4 years ago. I've had 30+, without too much of a focus on it. Of course it's not 100 of players with that amount, but still...
Anyway, I agree with the criticism leveled against the guide - namely that the resource cost for much of what you advocate is simply not worth it. However, I'll still commend you for posting the guide Hopefully some new players will realize that CP production is important (without following the guide 100%).
