Ey, Harvest Moon was one of the first games I've ever played in my life, and I loved Stardew Valley too..but I agree with it's limitations.
What upsets me a bit is that many games, as I've said on my last reply on this thread, are 'limited by existant conventions' of their genres.
I see very little innovation on the AAA/mainstream circuit (except for graphical and technical stuff, which will always change), and some of that seem to be leaking to the indie side of things. It's annoying that even though there are clear niches out there, people don't fill it. "Stardew Valley sold more than Call of Duty on Steam", yet the 'social farming simulators' that try to emulate it manage to be worse or even more limited. Or even worse..they base themselves completely on a game that was released 20 years ago.
The reason I love games like Prison Architect, Rimworld and Startopia (that's an old one), is because they executed concepts beautifully on the right place, right time. Even though DF existed, Rimworld still manages to make itself unique.
These types of games bring me that feeling from the 90's and early 2000's where almost every game you'd install would be its own thing (would at least try to stand out). Even being influenced by this or that, it would still bring surprises.
In my mind, every game that makes you feel that way is worth the time of a DF player, no matter the genre or similarity to DF.
I don't think what's wrong with Stardew Valley is the art or the dialogues..it just feels like a 90's game in a post-Minecraft wrapping.
I'm not saying this is bad, though, SV was developed by a single dude and I think it's a great achievement.
I should've warned about this post being a random rant in the first line. I also could be wrong, since I've been feeling way too pessimistic about videogames, which is my own fault.
