hiii! thank you so much for the kind words. ♡ happy to have you here!
no need to apologize! i don't mind questions at all. i don't have many tips gameplay wise, so if you don't have an experience with isometric RPGs, i would advise you to keep the tutorials on. it's a bit of a learning curve if you're not used to it, but it's not super hard to get into. the game is really fun once you get the hang of it.
as for character creation, i am a bit of a mod whore and use several mods in almost any game i play. that being said, the vanilla game still has tons of options to choose from to customize your character. i would def boot it up w/o mods first to play around with all the options and see what you can come up with. i usually have an idea in mind before i create a character, whether it be a color palette i want to experiment with or just a random idea that popped into my mind from a quote or song i'm listening to. however, there have been times where my characters were purely born from seeing a certain mod and wanting to create a character with that asset. (like horns, hair, tattoos, a modded head, etc.) i tend to lean more towards elves or horned characters, which is the whole reason i have so many tieflings lol. horns, fangs, and pointy ears? sign me up!
as for their backstories/personalities, it all depends. there have been times where my characters backstory was already forming before i made them, like my werewolf Ylva, and there are other times where their story came much later after their creation, like Khione. i will say the majority of their backstories come after i've made them, and i play around with dialogue options in game to kind of flesh out what feels right for them. i also keep a personal Discord where i ramble when the ideas hit me and individual Pinterest boards for inspiration on their personalities.
i hope this helps! just know there is no right or wrong way to breathe your characters to life. sometimes their stories or looks might change drastically after you've started playing them and you switch it up, but it's so fun once that creative wave hits you.
i also have a page where i list all the mods i use here, but please be wary that some contain spoilers for the main game, so i would def run a vanilla playthrough first before playing with mods. i also have some that are personal mods that aren't released, so always feel free to ask what outfits, accessories, horns, faces, etc i'm using on a certain gifset and i'll do my best to link them for you!
