as a group we tend to build to accommodate the 8 people within the group, this does lead to a base that seems larger then those around us, a farm that is slightly bigger etc. we also have "fun projects" like a hotel, nail tag, gallery etc for the server to enjoy and rather then plonk up wind turbines on mass we avoid this by using test gens, i feel we are not the only ones doing this as we all tend to talk to one another (within the main groups within the US scourge community) and try to help with lag etc because we want to play without the spikes and issues.
it does become a bit costly however for those of us that do purchase them every wipe, with the intention to help keep the server lag free.
