You know the feeling of starting a new mmorpg video game? The first time you enter a new world, you dont know what to do, where to go, there is no "optimal" way to play it, there are no guides, you just try things and explore and play and have fun. Every new project I start I have this feeling.
Few years later the game is a chore, you have daily quests, guides and optimal strategies and simmulations and if you dont play what elitistjerks say you are doing it wrong.
With AI it feels the game is never new.
