Yeah, I can't believe I am doing this, but I am going to play devil's advocate and attempt to verify why Maxis isn't going to increase city sizes. People are complaining all the time about how Maxis is lying about how it can't be implemented, and I want to show that there is some truth behind their claims.   My Specs Windows 7 Pro Intel Core i5-2520M @ 2.5GHz (dual core w/ hyper threading) 8GB of RAM AMD Radeon HD 6770M w/4GB of memory As you can tell I don't have the most amazing gaming PC in the world. (it is a laptop, if you couldn't tell by the CPU and GPU) I think it is representative of "good enough" enthusiast gaming hardware, which I would assume is the main target for most AAA games. SimCity has a much more diverse install base than something such as Crysis 3, for example, so I can see the average specs of a SimCity player being considerably lower than these.    SimCity's Resource Usage I used Windows Task Manager to measure the resource usage of SimCity while playing on a reasonably demanding city. Let's start with the RAM usage of SimCity alone.     This is just showing that SimCity is using ~1.18GB of RAM. Normally that'd be pretty low, considering I have 8GB of ram to use. However, SimCity is running in 32 bit which means it can only use up to 4GB of memory at a time. This dramatically limits the size of simulation SimCity can handle. Consider the fact that the layout I was using for this city was by no means the optimum layout to fit in population and that there is easily potential to fit in several times more sims than I did. (My population was around 130,000, but I think it can get as high as 600,000 with some layouts)   Taking this into consideration, my resource usage was far from the highest it could be. Even with the small city plot sizes, I feel that reaching that 4GB limit is closer than some might imagine. If I were to continue the same non-optimal layout and make it four times the size, I am sure I'd be well over the limit. The easiest solution I see for this is for Maxis to distribute separate 32 and 64 bit versions of SimCity, but I am not sure how difficult that would be to do.     Above you can see my total CPU and RAM usage from all of the programs running on my computer. In the previous image you can see that SimCity's CPU usage was at 36%, meaning only 1% of the other CPU usage was from programs other than SimCity. This is another place where we will hit a limit. Theoretically quadrupling the size of the simulation would also quadruple the CPU usage, (not scientific) which would put my CPU at 144% of its limit.    Conclusion I think I have showed why implementing larger city sizes is a challenge, however this is a piss poor reason for Maxis to not include larger cities. They should see this as a reason to implement smaller cities to fall back on, but they shouldn't have let the fact that most people couldn't run it prevent EVERYONE from running it.   PLEASE try to prove me wrong, as I seriously hope I am. SimCity is a game I enjoy very much and would enjoy so much more with larger map sizes. I just don't want to get to optimistic about that happening in the near future...
