It’s Pong! The grandaddy of them all. Well, okay, not the absolute first ever computer game ever EVER, but it was certainly the first widely successful one.
If you have the slightest familiarity with gaming, surely Pong needs little to no introduction, but you might be surprised to know that it actually still holds up rather well today. It’s gaming stripped down to its bare essentials, both in terms of graphics and mechanics — and it still works wonderfully as a competitive game.
Fortunately, with how well-known it is and how easy it is to program a convincing clone (even I could probably do it if I tried hard enough!) there’s no shortage of ways to play it these days… but if you really want the true experience, you gotta go Atari.
