How decent should the writing be to keep you engaged in a game? (Assuming we're talking about a game from your favorite genre.)
By average, I meant agreeable writing without language errors and such. It necessarily won't feel as good as content coming from a native writer, but I'm confident that many would find it enjoyable if I did other things right. In any case, I do have a native-speaking pal who's willing to point out my mistakes and even rewrite dialogue where necessary, but the problem is I can't ask him to do my work for me. So turning my imagination into words will be largely up to me, even if the process isn't perfect.
Thank you.
Wait, hold on. You're
not a native English speaker? From just this small paragraph, I'd say you're a lot better than half of the native English speakers I've seen online.
There are people who like to go around and say they're bilingual or multilingual but it's usually just a half-assed grasp of the second language and then filling in the blanks with memes or random slang. I haven't seen any of your writing but I feel like just from this, you seem to have more than enough fluency. I'm sorry for wasting your time by harping on the grammar part so much.
If you're trying to figure out how to write a story that will keep people engaged, maybe just study some of the VNs that are praised for their writing. "What did this make me feel?" "Why did it make me feel that way?" "What exactly did the writer/dev do here?"
The individual scenes, the overall plot, various "tools" (music, scene transitions, free roams, etc.) that are used to convey lines in a different way or give it emphasis. One advantage of a VN is that you can create a sort of unique way of telling a story that's not expressed just through the writing. It's easier to "show, not tell" in a game than it is for any normal, written story.
Being more well-read also helps to give you a deeper well of methods to express yourself in words. It can help make your characters seem more "human". Make people care about your characters. Whether it's to praise them or complain about them. Make them feel like they're their own people, not just a dude writing them to all speak the same way.
Building a vast world and exploring it or really knowing the subject matter of your story also just make for some pretty engaging stories.
There are also VNs that are really popular with mediocre plotlines but the gimmick and writing for scenes is what draws people in. Being a DIK being a prime example. Melodramatic plotlines with real world inconsistencies but what draws most people to it is how fleshed out characters can be through interactions, American Pie-esque hijinks, and the sentimental or exciting moments he can create in individual scenes.
Other VNs I can think of at the top of my head would be: MadWorld, Chasing Sunsets, A Father's Sins, Friends in Need, and Desert Stalker.
Each of them having something about them that make it feel like an interesting read. Whether it's characters you can sympathize with, every sentence feeling natural and meaningful, a thrilling and uncommon story that feels believable to some extent, characters acting in a way that feel real, or intricate details in an open world.
I went on a rant. Sorry about that. Feel free to ignore my presumptuoness if there's nothing useful to glean from my crazy babbling.
