played with swiftus a little bit, few things I notice
you cannot build a do it all city.... city is way too small. You also need to be efficient on space. Proper zone planning is crucial.
You can pretty much build a city in 3 hours, if you don't really care to make it pretty or high density. However if you want to build a wonder(SC5 call it great work) you pretty much need to have 2-3 city link together knowing everyone's supplying as each map have limited resource.
Another huge help is build a utility city, utility building are expensive and cost an arm and a leg to maintain, but you can 'lend service' to your partner to offset the expense. In fact almost all resource in game can be shared.
Since it is a free server, chat can be delay for up to a minute, and often times I can see swiftus going online and offline.
We are currently in USA west server due to East being completely hammered with a login queue of up to 30 minutes.
