So, it took me over a hundred hours but I managed to 100% Stardew Valley. So now I'm obligated to give you my opinions on it!

PROS:
-Lovable Characters
-Charming gameplay
-Simple yet visually pleasing graphics
-Goals to work towards

CONS:
-You either love or hate fishing, there is no in between
-Completing the museum, much like in Animal Crossing, is a ♥♥♥♥♥
-If you're a baddie like me, dungeon delving is tough
-If you want to 100%, Fector's Challenge/Journey of the Praerie King in general is a ♥♥♥♥♥

Regardless of the downsides, this game is very reminiscent of Animal Crossing and Harvest Moon as I'm sure you've heard already if you're looking over reviews, which is very accurate. I was generally more reminded of Harvest Moon than Animal Crossing, however the characters are more fleshed out and realistic than what I've seen from either series. Also something to keep in mind - don't take this game too quickly like I did; I was in a bit of a rush to 100% complete it, and kind of missed out on the joy of taking my time in the game and enjoying it, which I regret. You can easily spend over 200 hours on this game when taking your time, and I recommend taking full advantage of that.
