Retro games represent a lot of things. At their simplest, they’re a way for people who played the game when it first came out to reconnect with the game. A lot of formative gaming memories are powerful experiences, and reliving those experiences will give you a new perspective or better appreciation of what you played. Also, you might realize that the game wasn’t quite as hard as you remember it. That’s always humbling.
They’re often also still great games that stand the test of time. Great writing, art, and gameplay doesn’t age. You can pick up a classic RPG from the ‘90s and enjoy it just as much as a modern game, with the added bonus that it’ll probably run extremely well on almost any hardware.
