... you're getting into your car after work, glance to your left and see a small pile of pink-ish material a few feet away and your brain instantly says "Hey, someone dropped some fishing bait!". Ok, I lie... there is no such thing as too much SDV!!
Oi. I had to dig back 46 pages for this, but: http://community.playstarbound.com/threads/you-might-play-too-much-stardew-valley-when.123588/ Thought that might interest you. lol
You set an actual rooster sound as your alarm. You carry dozens of jars of pickles with you to give to random people. You get arrested for carrying a sword and explosives in public. You go out with your friends for drinks but leave early because you don't want to get billed for staying out too long. You're astounded by the amount of dialogue your spouse has. You wonder why the rainforests have to be protected. Trees take just one season to grow, right? Cooking programs on TV suddenly become interesting. You eat your dinner by throwing it into the air and catching it with your mouth, wondering why noone invites you to dinner anymore. You see a backpack for 39,95 and think "score!". You try to carry 600 pizzas in your backpack. You don't drink cola anymore because it's trash and made by JoJa. You cut down random trees and get arrested for that. You're desperately looking for the perfect piece of cheese just in case a random Luau comes up. You keep food in your fridge for years and are seriously baffled when it spoils. You suspect JoJa interference when the local government does not allow you to upgrade your house. You go to the nearest bus station but can't find a bus that goes to a desert. You live completely self-sufficient.
...When you eyeball the fruits and vegetables at the grocery store and remember how much they cost per quality on SDV.
... when you have your first baby in SDV and you can't stop staring at it, thinking "It's the most adorable thing I've ever seen!".
You're at the pub when somebody mentions trying a blueberry beer and you wonder how they got it to turn into beer instead of wine (and you have a tiny freakout moment of trying to remember if you harvested in the greenhouse today). You're making your grocery list and automatically imagine all produce in its pixel form.
Just passed a fenced-off empty lot near my place that's turning itself into a meadow and my brain automatically said, "Wow, they sure planted a lot of grass starter this season."
You expect your crystalarium at home to clone diamonds, while knowing perfectly well that in reality it can only duplicate paper money.
There's currently a storm warning for my town and my first subconscious reaction was "Yay, battery packs!".
I had just played through berry picking season and was driving to the store and saw a bush with a bunch of pink flowers on it and immediately wanted to run over and shake the bush.
Ok, I just had one happen yesterday. I was at the grocery store and the lady in front of me put a huge bundle of garlic on the counter. I saw it and immediately thought "Oh yeah, I need a bunch of garlic to make Oil of Garlic for the Crafting achievement! I should go grab a bundle!" After all this time, it still happens...
