Lol, I was you 10 years ago. For context I'm Malaysian and we only drink water that is first filtered and then boiled. When eating outside we generally avoid iced drinks unless it's a reputable shop.
Then I moved to Australia and reacted with utter horror to see my then-bf drink straight from the tap. I was like wtf you're going to get parasites! Spit it out!
Now I drink water like Aussies and my kid refills her bottle from the tap too. My parents, when they visit, still boil water to drink but they've at least stopped thinking we're trying to murder their grandchild.
I second Genshin Impact, it's a great game I've been playing for I think 3 years now. Graphics are beautiful if your phone can handle it. I've been buying the monthly card (8AUD) for a year now and I never buy crystals; I find that's an affordable way to support the developers and satisfy my need for new characters.
Unlike other free games there's no annoying popups or exclamations marks to push spending on you too so that's great.
I grew up in Asia so I'm used to gacha games, but I understand western gamers might have a problem with it. If you have a gambling addiction or FOMO then this is maybe not a good rec.
