OLD FORUM ARCHIVE

Whilst EA didn't archive the old forum, the Wayback Machine has multiple copies of the forum dating from a long time ago!

Command & Conquer - English — EA Forums (archive.org)  is from the previous one which ran from around 2017 until 2023.  Unfortunately the German language version appears not to be archived in depth.

Not every post/thread will necessarily be there, but looking around i've found quite a few.
