Halo, but probably only because of how long I've been with it. It was the reason I got my first OWN gaming console back in the late 2000's, and I'm hyped af for infinite.
Ratchet and Clank is one I hold dearly. One of the older games (can't name it off the top of my head) of the franchise is the first videogame I have clear memories of playing. Along with Jak and Daxter iirc, but I didn't really follow it as much as I do Ratchet and Clank. Even though I don't own a PS5 I'm still hyped for the new one as I even played the PS4 reebot.
I rlly don't know another one as I don't follow franchises, I just play games. But the metro series is really good, so that maybe.
