Nintendo has been very active with the Nintendo Switch Online retro libraries lately. Although it varies which retro library Nintendo updates, Nintendo’s schedule with new additions has reached a point where it is guaranteed to see at least one retro game added a month.
For example, Nintendo has officially announced that The Legend of Zelda: Oracle of Ages and The Legend of Zelda: Oracle of Seasons are now available to play for Nintendo Switch Online members, via the Game Boy library. You can see their announcement tweet down below.

Well that was out of nowhere. Hyped to revisit these. I know exactly where i was when i played. I had ages and my friend had seasons. Was on a class trip to england. Good times.
I think there was a rumour not to long back that said we’d be getting something Zelda related soon, so I’m guessing it was true/lucky guess that we did get another Zelda title
Never played these two it’ll be a new experience for myself, im happy they released them at the same time.
Can you imagine the backlash if they only released one of these?
