Back before games had cinematic intros, and many of the biggest titles were still in arcades, the video game title screen was often one of the most important "lures" for a customer.
Featuring big artwork and even bigger titles, it had to capture everything the game stood for. Everything it was about. Everything it was trying to sell to you, the consumer.
These days, of course, they're less important. They're usually just the things you end up on if you leave a controller idle, or are an obstacle you have to mash a button to get past in order to actually start playing.
Yet the art remains. And Please Press Start is doing a great job of cataloguing its more recent entrants, with an ever-growing archive of screens asking you, usually very politely, to please "Press Start".
