As far as personality, he is very nice, and a little bit outgoing and active. But David is quite sloppy, and somewhat serious. When it comes to his skill points, he is close to maximizing the cooking skill, and is on his way towards maximizing the logic skill. Phil is mostly interested in Weather and Crime.
He has the same facial structure as Paul Fairchild. David's name is randomized when Exotic Destinations is generated. The name "David McClellan" is only referenced in the game files. Strangely he has the memory of meeting an unknown Sim, probably a result of deletion.
Do NOT attempt to make David selectable, or tamper with him in any way or form outside of his in-game designated purposes. Doing so will corrupt the neighborhood he is in.
