From the Mongoose website:
The 25th Anniversary of Paranoia (contains) new rules to ignore, and new missions to be excited by.
PARANOIA: A light-hearted game of backstabbing, treachery and guile, where trusting other players is a sure route to the termination centre. Get paranoid. Or else!
PARANOIA IS FUN. OTHER GAMES ARE NOT FUN. BUY PARANOIA.
Furthermore, also from the Mongoose website:
Paranoia is the best RPG ever released. Other RPGs are not the best. Buy Paranoia.
The current* (perfect) range of Paranoia products will be retired at the end of this month to make way for the even more perfect 25th Anniversary line, starting with the Paranoia: Troubleshooters rulebook, and the Black Missions limited edition. Rumours that the current range of supplements will maintain a 90% compatibility rating with the new Paranoia books are treasonous. Report all rumours immediatly.
- "Current" refers to the line formerly known as "Paranoia XP", known now only as "Paranoia" by request of Microsoft.
