Edit to add: coop multiplayer is not available on the mobile version, which is the only realistic choice for our current life pattern / technology setup. I do agree it sounds interesting and fun!

My family has recently been on a big Stardew Valley kick. My spouse and I and our daughter are all first time players playing on android, which has no multiplayer mode.

From what I understand about multiplayer, I don't really think it would be good for us. We all play the game in very different ways. However, I think it would be amazing to be able to trade items. No one but me likes going into the mines/caves, and sometimes you just need one of something out of season.

My idea is that there would be a special chest I could put something into and it would be moved out of my game and into one of theirs or vice versa. Obviously, you could mod the game so you can just get any item, but this way somebody still has to get it, so it (hopefully) doesn't undermine the game economy.

I have been looking at the mod community, and it seems like the android version supports mods. I haven't found a mod that does as described. My general path forward is:

• set up a mod that implements the chest and talks to a server via API
• set up a server that can receive and hold incoming "put" and then send those items with the "get" from the client at the other end
• build the API so that it can represent important assets in the game
• come up with a lightweight way to secure the protocol to the intended users (this may depend on how identifiable individual clients are, but could be as simple as putting in a shared secret when creating the chest)

Obviously there are a lot of details to work out, but I wanted to get some wider feedback from people who had been playing the game longer.

• does this already exist and I'm just not aware? I did spend some time searching, but it seems like most mods are either cosmetic or change the in game mechanics in some way.
• would you be interested in something like this?
• what kind of mechanics would you want to see? Maybe a way to propose and accept specific trades rather than just sending items? Would you limit it to your circle of friends or be interested in a wider community?
• have you written or used Stardew Valley mods (especially on android), and if so, what was your experience?

For those not familiar with Stardew Valley: Developed by ConcernedApe, Stardew Valley is a farming simulation RPG that can be compared to Harvest Moon. Quite enjoyable solo, even more fun as a multiplayer game with the new update. Available on the Switch as well as other consoles. Currently the MP is only available on Steam/GOG.

Are any other Tildes playing? Have you tried modding (on PC)? Who's your waifu/husbando?
