The only games I'll bother keeping installed that are over 100gb are my ESO with all the addons on PC, and Star Wars Battlefront II on PS5, and only because my friends and I play co-op every Friday night. But it's still ludicrous. My most played game recently, Battlebit Remastered, is a whopping 3 GB lol.
I was going to install CoD: Cold War from PS+ on my PS5 since I wanted to check out the campaign but I'd never buy it. Fuckin 230 GB for that shit. I lol'd a bit and moved on to something else. So ridiculous.
I'd look at Telltale-style games. They're roughly 10 hours each ( five 2-hour ish episodes) and are almost entirely story driven. The gameplay is usually very simple. You choose dialogue choices to drive the story.
The best Telltale games are in my opinion: The Wolf Among Us, Tales from the Borderlands, The Walking Dead, Batman: The Telltale Series and its sequel, Batman: The Enemy Within. They're also releasing the first episode of The Expanse (based on the TV show since the character Camina Drummer does not exist in the books) later this month.
Another series that is very much that same style but by different devs is the Life is Strange series. I've played the first one and the prequel called Before the Storm. They are very emotionally heavy stories so I'm taking some time before I can go into the sequels but I absolutely love that series and will preach it to anyone who will listen.
10 hours is definitely short but it also helps that they are all done in 2-hour episodes so you can easily take breaks.
