Quite a while ago a leaked 3DS eShop listing outed a re-release of Mario & Luigi: Superstar Saga, and it's now been revealed during the Nintendo Treehouse stream at E3 2017. Mario & Luigi: Superstar Saga + Bowser's Minions will arrive on 6th October.
You can see a trailer below, which shows the + Bowser's Minions part of the name as related to new content where you bring together enemy characters in an army to rescue the big boss, led by 'Captain Goomba'.
As you can see, the visuals adopt the style seen in the 3DS-generation Mario & Luigi games, which is a very welcome touch.
So, are you excited about this one?
