So games from Paradox become retro at 18 but games from the USA don't become retro until 21?I sort of have a flexible personal limit on what is retro and that is, if it is old enough to drink, it is retro, ie 18 (here in swe). But i can stretch that a year back and forth depending on the game.
So how should we do "retro"? Everything more than X years old? Everything from year Y and earlier?
We shouldn't get tied up in defining it, and avoid "That's not retro" "It is too!" wars
If you think it's retro, post about it.
No new game released in the last 20 years is retro.
All games over 25 years old are retro
there is a 5 year grey period where it could be maybe retro
I don't think retro should be defined as a specific subset of games. I would say it's more like nostalgia, something that reminds you of "the past", where the cut-off for what is considered "the past" and "current" is different for different people.
Just off the top of my head I'll list a handful of games that I think are retro, : the Wizardry and Might & Magic games, the Ulima Games, the Realms of Arkania games, Gabriel Knight games, Lands of Lore, Betrayal at Krondor, Fallouts 1 &2, even the 1st Diablo. All of those are retro games to me.
