For me the issue if lagging is a thing if the past unless the user has a multitude of layers then I lag really bad. I run with 8 gig of DDR3 ram which in essence is 16 gig of ram and a 2.4 Core 2 Processer. and the Latest version of Adobe Flash. Though I understand the limitations with Adobe. Maybe Adobe and the developers can address that issue and maybe develop some why where everyone can be happy.
Just because you have a supper fast computer doesn't mean everyone has a computer that fast. For you to expect the game to be catered to a very small group of people that have a really fast computer is stupid and unfair to the rest of the people playing farm town. There is no way bigger farms would work it would be too much of a drain on people's computer AND the farm town servers.
