I own Stardew Valley but I am avoiding using the Google Play store when possible. While I could just sign into Aurora Store with my Google account I think I'd need to install Google Play Services so I am wondering if I could crack the game myself. I think in the past people used Lucky Patcher but I have tried it with other games that I own with no luck.
I've looked through the megathread and it seems like there are versions of Stardew Valley uploaded to Mobilism but a majority of them are modded for things like infinite stamina and money. The version without mods on Mobilism also appears to be re-uploaded from Apk Vision which isn't in the megathread.
you can't download paid content using Aurora Store. it uses sockpuppet Google accounts to download from the Play Store's servers (which is why half the time the accounts are rate limited and don't work anyway)
You can use a valid account if you want.
