I second mynewnickname's recommendation of the Common Sense Media website as an excellent resource for researching games like Fortnite.
Generally, I've discouraged my 9yo from playing Fortnite at our home b/c it just doesn't strike me as educational at all. (I also dislike the "last man standing" aspect vs collaborative, creative game objectives, and I also prefer that he avoids guns in games to the extent possible.)
You might check out my.youthdigital.com for creative coding projects and education. My son took a coding camp last year, and it included a year's access to this site. Or, if his school has computers or a computer class, you might ask the teacher for some coding game/website recommendations. Finally, I see you're located in Pittsburgh, so maybe Carnegie Mellon University or UPitt Computer Science program administrators could recommend some good kid-friendly programs.
I'd like to recommend coding camps, but frankly I'm shocked at the cost! We managed to find a Pacific Science Center week-long summer camp for under $500 (it was held at one of our local community colleges), but most Seattle area coding camps are going for well over $800 (some as high as $1200)! How on earth is pricing like that making this kind of education accessible to regular people who are just trying to teach their kids valuable skills for enrichment and future job success!?! I'm sorry -- I don't mean to get on a soapbox about affordable enrichment, but it's a real pet peeve of mine! I encourage you to dig around for an affordably priced community center coding camp in your area.
Good luck, Viola! Your kiddo sounds like a great kid :)
