Stardew Valley could be compared to Harvest Moon series (I say that having not played the SNES original of Harvest Moon or the subserquent GBA releases but I have played the first GB release) It's similiar in premise, and many game play elements (such as hay feeding of livestock) This game is not just a reboot of another game but it is something else wonderful in it's own right and does (almost) everything right. It made me think a bit of Earthbound in the way you visit the local town to talk to people and do your shopping. It's also somewhat wacky at times in the way some RPGs tend to be with NPC interaction. A lot of rather nice subtle things seem to be simulated as you play it. One of the nice things is the diversity of work paths. Would you like to get your work done, or would you like to go to town? Maybe take a day off, go to the beach and go fishing? What about exploring the mines? Maybe leave town? The way the passage of time works, you have to plan your days, and how you use your time. This simulates many rural communities where you either work or go to town. The real nice thing is the town inhabitants and your interaction with them. This is what turns the game into a full blown JRPG in the purest of essence. You have choices, decisions, relations with the town inhabitants, and you build those relations over time. It feels very sim-like and over time as you build these realations with the town inhabitants it VERY much does simulate life in a rural community, where relations are tighter, and people know each other. One weird side effect I discovered in playing this game, is that when i tend to play it, I am a bit sick of the urban-induced stresses and conveniences of modern life as described in the cheesy intro. How odd is that?

However, I also find the game gets tiring. As you get into it, there is JUST SO MUCH WORK. I gifted and improved relations with all NPCs to see their special scutcenes rather than pursue a wife/husband to share workload (my favorite part of the game, was actually these cut scenes to get a feel for each of these really nice and unique characters in the town of Stardew Valley) By the time I was ready to marry, I pretty much had finished the game. In any case, this game is a 5 star title hands down for every detail of it's design, its attention to detail to the retro stylization resembling the HM series, the fact you can do so much in it. The way you interact with the villagers. The decision making and time planning components. The many myriad cutscenes, festivals in game events and more. There is just so much to explore and do in this virtual environment that some players could really spend a loooot of time in it. It's a fun game to just do things and explore and figure things out.

The way seasons work adds variety and change to your in game world Trees look different, harvesting works different, fish you can catch are different. Villager activity is different. Very nice. Plants regrow, lots of things appear to make the world in SV seem alive. (A lot of thought was putting into exhausting the possibilities of random ingame events.)
My only criticisms with the game is that it would also be nice to have some hints of what gifts you can give villagers rather than look it up, or figure it out. (I find myself lookin up stuff on the wiki constantly, and it just breaks immersion) Time to time some villagers will say 'so and so really does not like such and such' but its few and far between and not quite enough to build on, gifting is a big part of the game, since it fuels the relationship building which is a major component. I also really was not a fan of the fishing. It is very much reminiscence of some of the super japanesey fishing sims on super famicom, but the fishing was a bit mechnical and not a very fun minigame. (at least not for the challenging fish as they are impossible to catch)

My other criticism is bugs. The game has some very unusual and diverse bugs. Some will halt cutscenes, some will make you extra money by duping items when harvesting (that's okay, haha) but most are frustrating due to crashes that occur at EOD in game because of something you did (you can't quicksave so if crash happens you must repeat the day) As best I could tell, I found that if i did certain tasks it would ruin the day. So I would go do something else and eventually it would let me. There were also some steam achievements going one with the GOG version that would cause crashes. You can find a patch for that online (such as going to the bottom of the mines) Ultimately nothing game breaking.
There is so much in this game and it's done so well I still give it a five star rating despite the bugs. I highly reccommend this game if you like stuff like HM, evoland, or Earthbound. Maybe even the sims, or zelda or any kind of retro Action-JRPG styled games. Starbound and Terraria players seem to like it too.

This gem of an indie game is the most addicting thing I've come across this year. It immediately sucked me in like I hadn't found myself pulled into a game in quite a while. I try not to be a hipster about it. But it amazes me when indie studios come out with things like this. Painstaking design and attention to detail, creativity expressed, everything you would expect but do not always get: I love these true retro graphics, fantastic portrait art depicting NPC emotions. the Player character who jumps and expresses himself in his own chronotrigger type way. And some really clever use of the layered backgrounds for art/overlay that is still true retro aesthetic. Stardew Valley is the excellent kind of thing that happens when a small studio has a consistent and uniform vision.
