Online was there, but consoles weren't built around it like they are now. Technically, there were download-only games in the 80s, but they were an oddity.the7k wrote:Offline makes it retro? Online gaming has been a part of gaming for a long time, at least since the 90s.
I think retro, at least as I see it, is best shown by genres. Platformers, fighters, shmups, beat 'em ups, survival horror, arena shooters, competitive puzzlers and roguelikes are some genres I'd consider retro regardless of age, DLC, online functionality, etc.
Any console you buy now more or less expects a broadband internet connection, and offers a fair bit of content you can't get without one. There's a huge difference, in that regard, between a PS2 and a PS3. Not so much between a PS3 and a PS4.
Pretty much every genre you mentioned never stopped getting made. If they're considered retro purely on those merits, it'd be, perhaps, because the heyday for the style has passed. However, what would you classify games that remove the advancements of the genre as then? IE, a fighter that doesn't have super meters, counters, cancels, and whatever other elements that nearly anything now incorporates? That would be retro. A 2D fighter in general is just niche.
