Airport CEO started out in Early Access on Steam and, like so many Early Access games, the developers never bothered to finish the game. They took it out of EA and dropped it like a hot potato as soon as early access sales started to dwindle and they lost interest in continuing to support it. The now-abandoned final product is riddled with bugs and lack of content, though the user-created content does fill some of the gaps. Problems with pathfinding. Problems with vehicles and agents getting stuck. Memory leaks. Frequent crashes. It's a shame because for a while it really seemed like the developers were committed to producing a quality product and the mechanics they did flesh out are good. But, since Apog has shown a lack of resolve to their players, I'll certainly never buy another one of their products.
