I still remember the old RTB USSR builds. They even made a reproduction of St. Basil's Cathedral in Moscow, Russia. Lots of neat stuff and great people.
On a slightly more related note, Afkpuz, who used to be in USSR is also active every now and then. Not to mention Ronin (where are you lately?) and a few others. Funny, thinking about USSR brings back my late-teenhood. Yeah, it's been a while.
