Hello Cozy_Luna and Welcome to the Forums!
Mmmm there's nothing quite like that first time Stardew Valley obsessplaythrough. Almost everyone would trade real important things like kidneys and ISP bills and their boss's lunch for a week for the opportunity to get that first playthrough again. Enjoy it and take your time. There's a lot of replay value (I have like 7 Farms) but butbut there's that first one... and then all the others.
I'm kinda on a hiatus from SDV right now but my most active farm is my Slime Farm (started life as the Hilltop Map but I changed it to the regular map with some unintended consequences). And the only Farm I've kindasorta "completed" is my Ostrich Race Farm which is on the Beach map. There small complications like no Ostriches on it yet so not much truth in advertising there, eh? Hence the "kindasorta." Married to Haley on Ostrich Farm because some people were not terribly fond of her so I pretty much did it because that. Turns out she's a hoot, best spouse yet! Married Abigail on the Slime Farm as she kinda matches the theme and for the opposite reason as Haley, everyone was singing her praises and I wanted to see why.
But for favorite character, it is and always will be Gil. He is my spirit animal, my muse, my unattainable goal of perfection. Never moving a muscle, always fully at rest, making everyone else's 'lazy' seem frenetic, including mine. Scientists use him to calibrate the Kelvin scale once a year. The barest breezes threaten his motionlessness but somehow he naturally counters them in some unmoving way. I think it's magnets but Marlon won't let me get close enough and usually threatens me with an Insect Head.
Joke's on him, I find the Insect Head very pleasant to wield.
