Even though it is C# (that is not C++ :)) I was quite excited to learn about possibility to mod Skylines. On the other hand it is better that what it seems to be the case for SimCity 2013 – JavaScript! No pointers, no memory management – on the second certainly a better idea for the masses!
I have used C# before and I am quite comfortable developing with Visual Studio. I have looked at a couple of mods, some of them are just one-liners, but a few like Traffic Report tool (current is 1.4) are totally game changing (pardon the pun). The author started working on it on the next day after the official release date! Overall I am quite impressed of this kind of dedication and hope to use it as an inspiration!
