I simply don't care if Maxis allows it or not. If a mod is available (or doable if I want to do it by myself) and I want to try it, I will (on my private region btw).
I want my simcity to be modable... Maxis choose to insist on the online aspect of the game, which complicate the "approach" they'll do with mods, but that's not my problem, that's theirs... Mods are doable/available and I want to try them ? I'll do. Maxis is unhappy? just give us an offline patch and stop whining us with lame excuses for not doing so.
I also don't want to limit the term "mod" to some retexturing/redesing of some bats, I want them to be able to affect the gameplay mechanics, and Maxis already started calling that kind of mods "hacks", which they are not... They're additionnal gamedata loaded just like other gamedata, so they're mods. no matter if they so poorly coded the data loading engine that it's able to affect some mechanism they don't want to.
I bought a product, I see no reason for not being able to use it as I want and not as I'm dictated to want. At least as long as I don't play in public games. If they wanted to do a closed-environment game, they should not have done it on pc, but on consoles.
Btw, nice to have a little road for pedestrians available in the road menu.
