Chase GilsCarbo is one of the pre-made downtownies in The Sims 2: Nightlife. He can be made playable by befriending and asking him to move in, or by marrying him. Chase's career is randomized at the start of the game, and he is mainly interested in Environment, Food, Weather, Politics, and Entertainment. Judging by his looks, he may have Asian descent. Chase uses a slightly customized version of the 10th Maxis face template in Create a Sim.
His name is randomized when Downtown is generated. The name "Chase GilsCarbo" is only referenced in the game files. Despite being a Popularity Sim, he has the lifetime want to reach the top of the Science career. This want makes him compatible, at least in theory, with a Knowledge Sim, though he would have better chemistry with a Romance, Pleasure, or Fortune Sim. Chase is often known to annoy other Sims, due to his lack of nice points.
