Considering from what I've seen AI has better writing than quite a few games here; that's kinda the one thing I wouldn't necessarily mind. Also helps you skip the MTL as it can be written directly in english.
Not just a few, most. Lots of folks can't characterize at all, and suck at showing inner turmoil. So their "writing skills" end up completely falling into descriptiveness. Especially since so many plots have been done by now, I give lots of leeway on plot. Then just focus on descriptiveness and emotion. Which writers on this site by in large suck at emotional writing, and AI is actually pretty fucking good at descriptiveness. The main issue being sometimes it does it a bit too much, though you can usually get too a pretty decent level through just adjusting parameters. And if you have a high school level of literacy, you should be able to manually edit the AI writing by just toning down some bits.
Only issue AI really runs into is long stories it starts to lose cohesiveness. Though that's still workable assuming you can shortly summarize the main events before scene "x". And you'd get a better results than most writers here.
