Sigh, you really make it sound like we're bunch of cheaters or something with the "estonian style". We just know each other for long and we like to play in same nation. If someone is loosing turns then whoever notices it reminds him/her to log in. Our nation usually has biggest land, so we produce the most. We're usually indy too and indy nations usually have best NA. Other nations seem to be mixed or cashers or something, so it's understandable that they have less NA. (We have thought of being some other strat, but usually we have seen that there was enough cashers or farmers) Even without anyone reselling their stuff I'm pretty sure we would have good NA, and we have been doing it less and less. There's really nothing special or what you called "estonian style". We just have some good players who like to net in the same nation.
I've also thought of playing in other nations but as you can see I really like Sky, I don't want to leave,
. You just need some people who you like playing with and make a nation. If you don't do well in netting then try again next set but change something. Don't waste all your turns right away, be patient. Don't expand/build cs unless you're jumping or starting to loose turns, at least not before the jump. Make good grabs. If you don't find any then when you have some time wait for better ones... Now I feel like I'm telling things about netting that everyone already knows, but I really don't know what else to say... Sky is just good because our players are good.
