I do not recommend downloading any SimCity 5 cracks or keygens that you find listed in Google or on warez sites.
Why? They are all fake and will most likely contain spyware, malware and/or trojans etc. that will steal your Origin account or other important information
SimCity 5 requires an always-on internet connection (similar to Diablo III) so keygens and cracks are fake and will not work (at least for now!).
If you do want to play SimCity 5 you need to buy it through Origin (ugh!). However, I suggest a boycott of SimCity 5 altogether due to the DRM requirements!620 views
