TL;DR Retro gaming is playing games from past decades - on original hardware, through emulation, or via modern re-releases - for reasons ranging from nostalgia to genuine design appreciation.
Retro gaming is playing games from the 1980s through the 2000s (or earlier), usually via emulation, original hardware, or modern remakes. The community values these games for gameplay depth, historical significance, and nostalgia.
Origin & Context
Retro gaming as a distinct hobby emerged once console generations aged out of retail relevance but before anyone was actively preserving them - a gap where old consoles and cartridges started disappearing from shelves while a community of players who grew up with them kept caring. Emulation gave that community a way to keep playing without depending on increasingly rare, aging original hardware.
Why It Matters for Digital Independence
Retro gaming is a working rebuttal to planned obsolescence. Modern games often require day-one patches, online accounts, and live servers just to function; a decades-old game on original cartridge, or emulated from a preserved ROM, still runs today with zero corporate infrastructure required. Whether a major online-only release from this decade will still be playable in 2060 is genuinely uncertain - whether a classic 1980s platformer will be is not.
Real-World Examples
This lexicon covers the retro gaming ecosystem's specific pieces in more depth elsewhere - start with whichever matches how you actually want to play: RetroPie turns a Raspberry Pi into a dedicated retro console, MAME is the accuracy-first emulator for arcade cabinet games specifically, and RetroArch is the unified frontend for running many systems through one interface. A common pattern on r/retrogaming is people starting with one system that matters to them personally (their childhood console, usually) rather than trying to build a "complete" retro setup on day one.
What You Can Do
If you're new to retro gaming, pick a system with strong emulation support and personal meaning to you, and start there - RetroPie is the easiest single entry point if you don't already have strong opinions about which system to start with.
