The creator of Stardew Valley doesn't know if there will be another update, saying he's focused on his next game.
Speaking with Zach "UnsurpassableZ" Hartman on Twitch at the end of the first official Stardew Valley Cup, Eric "ConcernedApe" Barone answered a handful of questions from the community, one of which was about mods that let the player marry the non-marriageable people in the smash hit farming game.
Barone replied to explain why having almost everyone in the game be marriageable would be "just a tonne of work".
