Quigley (Maxim) says YES to modding! EA says NO, and we'll ban you and EA says YES, and we won't ban you! http://community.simtropolis.com/topic/55189-quigley-says-yes-ea-says-no-and-well-ban-you/http://www.reddit.com/r/SimCity/comments/1ab6cp/ea_customer_support_states_users_will_not_be/
i guess be very cautious before modding game!
also at the speed that things are happening we will have official answer soon as to what they are going to do, since some modder already created offline mode and other mods are popping up already that fix the things that officials said could not be done.
by the way the offline mode is just editing one variable, its a timer of how long to allow player to play without checking whether they are online, at present 20 minutes! so its all pack of lies from EA/Maxim.
i'll post links to mods as i find them
there appears to be an offline mod already!
with editing highways outside boundaries
and full debug mode
and that removes the fudging of population count http://www.reddit.com/user/trixisownedhttp://www.reddit.com/user/AzzerUK
more mods to come
right now its a little primitive, but it will get better
