Series like Splinter Cell, Hitman, and Metal Gear once dominated. But fewer stealth-focused games release today. Do you still enjoy pure stealth gameplay, or do you prefer games that just mix in stealth mechanics casually?
I don't think any game niches are outdated, some niches become less popular but game niches never become outdated. Sometimes they even make a comeback. The same goes with stealth games. I think they are less popular but I am sure they will make a good comeback.
