I often lurk in reddit, seeing what others are up to. This guy wants to adapt Stardew Valley. This is very much doable when it comes to the map, quests and npcs. However, the core gameplay loop would involve making a calendar system and a tracker for each individual plant's growth. At this point you're better off playing the game.
Adapting tabletop adventures makes way more sense than adapting video games. Sure, adapting Summertime Saga is much simpler because time doesn't matter there. You just have weekly schedules, not seasons. It's summer. Permanently.
A lot of games such as Stardew Valley, Rogue/Nethack/Dwarf Fortress/the Sims/Elder Scrolls/whatever simply play better than AI could ever do. AI adaptations for written word makes much more sense. If you're adapting vidya, you should stick to VNs, text games, and maybe RPGM games because they have a mostly set system and they generally suck to play seriously.
Making an inferior port of decent video games is pointless in my opinion. How can something with graphics and controls look better in text form?
