I agree on your other points, but I think Grandpa is largely blameless here. We only see him on a bed, which we can assume isn't in his farmhouse due to how he talks about Stardew Valley with the farmer. Regardless of whether or not that's his sickbed, deathbed, or nothing more than a great spot for a nap, a generous yet canonically-compliant timeline could be something like this:
1. Grandpa works the land in Stardew Valley until his 50s or 60s, raising his kids there and staying even after they move out.
2. Grandpa, finally too old to keep up with the farm work, leaves Stardew Valley. None of his kids want the Farm, but he keeps paying taxes on it in the hopes that perhaps one of his grandkids will.
2. Grandpa moves out of Stardew Valley to either live with his kids (the Farmer's parents) or just in Zuzu City, where medical care and senior friendly infrastructure are more available. He stays in touch with his family well enough to personally know his grandchild, the Farmer.
3. Some day, the Prologue Cutscene with Grandpa occurs, and Grandpa hands over the letter to the Farmer, the grandkid he thinks will most appreciate living on the Farm. This scene itself could easily be 15-30 years after Grandpa was last on the Farm, especially considering none of the Pelican Town villagers ever met the Farmer, even as a baby. Grandpa himself knows he's not going to be around forever, even if he is in good health. The Farmer is old enough to remember that day well, so let's assume that they're at least 10-15 years old, and at most, well that doesn't matter as much actually. I typically imagine the farmer in this scene to be at most around 20-25 years old for the whole "come here, kiddo" stuff Grandpa is pulling.
4. The Farmer, tired of their Joja life, opens the letter and moves to the Farm in Stardew Valley. This could be a long stretch of time if the farmer were younger and took longer to realize the emptiness of the Joja employment trap, but probably isn't less than 5 years. So let's say, the Farmer could have moved to Stardew Valley 5-20 years after the bedside cutscene.
These numbers add up to roughly 20-50 years of farm abandonment. That is a LOT of time. Even with 20 years, the Farmer is lucky that Farmhouse still has a working roof, never mind intact windows and zero woodland creatures living inside of it. A destroyed Greenhouse makes perfect sense from what we've seen storms do in-game (Lightning striking the farm 10+ times in a single day, the windstorm knocking down a Forest Giant that the Raccoons then live in). Grandpa could even have sold the raw building materials from his empty barns, coops, sheds (because he sold the farm animals back to Marnie) to Robin in exchange for her keeping the Farmhouse in working order. That Robin stuff is just speculation, though.
The giant rocks and logs aren't outside the realm of possibility for an in-game universe in which weeds, sticks, and rocks appear like manna every 1st of the season. In fact, you could probably do some sort of reverse-engineering on the Farm debris by clearing out the whole Farm and then sleeping every season away until the Farm is as messy as it was on Spring of Year 1. I bet it would give you a pretty young age for how long ago Grandpa left the Farm for the last time.
Anyway long story short, I think Grandpa arranged what he could but knew the Farm would grow out of control, and he probably wasn't swimming in cash and put the majority of his leftover savings into paying off those taxes for the decades between him leaving and the Farmer arriving. He knew clearing up the Farm would be hard work, but he knew we'd appreciate it because we'd love Stardew Valley, and because hard work builds character!
Yeah, this is a fair defense of Grandpa, honestly. I probably was being too harsh on him specifically.
If the farm had been abandoned for decades, then I can buy the rocks, weeds, broken greenhouse, and missing buildings. Nature taking over an old farm after 20+ years is not really Grandpa being negligent; that is just what happens when nobody is actively maintaining the land.
But I think that raises a different question for me: why was the handoff handled so badly?
Because Lewis clearly knew I was coming. Robin was there too. The farmhouse was at least livable. So some kind of communication happened. Grandpa must have trusted Lewis enough to act as the local contact, or at least Lewis knew enough about Grandpaās wishes to greet the farmer and explain the inheritance.
And that is where it still feels weird.
I do not expect Grandpa to have kept the whole farm perfect from a deathbed or from Zuzu City. But if Lewis knew Grandpa, knew the farm had been abandoned, knew the farmer was arriving, and knew this was supposed to be some meaningful life-changing inheritance, why did nobody prepare the farmer better?
Not even fully restore the place. Just basic care.
Clear a path. Inspect the farmhouse. Explain how long the farm had been abandoned. Warn the farmer that the greenhouse was destroyed. Maybe have Robin check the place more seriously. Maybe say, āYour grandfather loved this place, but it has been neglected for a long time, and it will take work to bring it back.ā
Also, the farm layout itself raises questions. Grandpa somehow had a greenhouse, but no leftover barn, no coop, no shed, no stable, nothing. I know this is mostly gameplay logic, because the player needs to build everything themselves, but in-universe it is strange. What kind of established āgreat farmerā has a greenhouse on the property but leaves behind zero other farm infrastructure?
Did he sell every barn and coop for parts? Did Robin dismantle them? Did the animals get sold back to Marnie? Was Grandpa mainly a crop farmer? Was the greenhouse the only major structure he cared about? I can invent explanations, but the game itself does not really explain it.
That is why the handoff feels so odd. Lewis treats the farm like a charming old property that needs a little elbow grease, when it is actually a semi-collapsed restoration project with weeds, boulders, logs, broken infrastructure, no farm buildings, and possibly ghosts.
So maybe Grandpa is not the villain here. Maybe the real issue is that Grandpa had poor judgment in trusting Lewis to handle the practical side of this.
Because the more generous I am to Grandpa, the worse Lewis looks. If Grandpa left decades ago and could not maintain the farm himself, then Lewis was probably the only person in Pelican Town who could have helped make the transition less brutal. And he just⦠didnāt.
That is what bothers me. Grandpa may have left the farmer a dream, but Lewis delivered it like an unpaid municipal cleanup project.
