The franchise that made me choose the 360 over the pc over more than a decade until I got tired playing it, and still I love this game. Gears of War 2, 3 and Judgment had fully offline support for cooperative and competitive mode, allowing you to play alone with and against bots in versus modes.
Regarding Gears of War 3, the mechanics are superior to previous ones. The campaign is awesome, finishing the story. Countless hours playing online with friends, I didn't care doing achievements and despite that, I happily did it. And even finishing all achievements, I still played it non-stop even with Gears of War 4 and 5 came out.
If is the original game or the rumored one "remake/collection or whatever it'll be", I want this game with no DRM and play it for the rest of my life. I don't care other more famous videogames. I only want these Gears games, these are the holy grail of videogames for me.
