I was wondering before and wanted to ask but reading the post on how Sega has to greenlight changes I am more convinced.
I work for CA, CA are owned by SEGA, as my modding is related to the TW series which we make, i had to have my mod green lighted by SEGA given the fact i am now a CA employee. The mod is not official or unofficial in anyway, i just happen to be a modder who now works for CA.

In my mods i have added in nothing that other modders could not do. There are not new speeches, i've edited the way reputation and diplomacy work like other modders do. I do have access to some things other modders do not, but i specifically do not use them as that is incredibly unfair and so i mod in the same way everyone else does.
