I explained this to my kid too. When I played like a decade ago there was like 1/3rd of what there is in the game now. I played Minecraft, but it’s basically like a sequel now.

I generally don’t keep mine installed all the time, but I keep one on hand just in case.

I take mine into the shower occasionally. Generally just to finish a reply or finish reading something. My phone is 4 years old and is 100% fine.
