Re: Code structure/design problems

Hi Oskar, I've been a game programmer for more than 5 years going from simple card games to 3D MMORPGs. Even though you can make a simple game in a functional way it would be a big challenge to do the same with a moderately complex game. Games are all about state, your character if full of state,
