I was reading the Zap adventure for Larry, Moe, and Curly Joe, their tics are really what defines them. I think that is very informative. Tics should help a great deal, in what sort of clone you want to play. Allows a way of role-playing that creates personality your player can use.
When RPG gamers in other forums talk about their characters, they rarely mention anything about their names or personalities. It's either this class or that class of character (I frequent the Conan forum, sorry!). I think as we continue to play Tics in this game, the more significant we will identify with the plight the clone finds themselves in.
I know some other games that push personality onto the player's PC, but Tics are more specific in action, and not general personality traits found in other unfun games.
I think this idea may just be the wave of the future of RPG gaming, and my hats off to the magnificent designers of Paranoia, and particularly to Allen Varney for being so responsive to our inquires.
