I've never really agreed with his attitude / his community's general attitude towards art and level design, but I always deeply respected Phillip's mission to exist as a hub for single player Half-Life 2 maps and mods. I'm sure it took a lot of work to keep the community running and to keep putting up new content, and I guess it was finally encroaching too much on his personal life and other projects -- so now it seems that Planet Phillip is going into a sort of hibernation.
Thanks for existing for all these years, Mr. Marlowe.
