You may recall that, last than a week ago, Nintendo had announced that you would be able to play Pokemon Stadium on Nintendo Switch Online + Expansion Pack on April 12th. As usual, the date was actually referring to Japan’s time zone, so April 12th in Japan would be late on April 11th or in the middle of the night for western regions, depending on the time zone.
Well, Nintendo has delivered on their promise. As of tonight, Pokemon Stadium has become available for Nintendo Switch Online + Expansion Pack members. Nintendo of America tweeted the news on their official Twitter account, so you can see their tweet about the matter down below.

I wanna be the very best
And no one ever was.

How many people do you think will be “sick” today, but mom i wanna play Pokemon Stadium!
It’s the school holidays here, so nobody needs to pretend to be sick.
Why is I that when Nintendo decided to put this game on the Switch, haven’t they thought about the transfer pack from Red and Blue? Nintendo sure is slow. Had it been Sony or Microsoft they would had done that.
