That's bull, if CA knows anything about writing good modular code half of those are not, repeat not major undertakings. So please stop saying they aren't realistic because they certainly should be.
Im sure they do, but this is for modding changes for PATCHES, something only a few devs work on, not for the next game. For the next game i'd love to have an sdk and stuff, but most of CA ozs resources are now on the expansion.
