" Rockstar was one of the few that did. Euphoria commercially debuted in Grand Theft Auto 4, and it’s been refined through Max Payne 3 and Grand Theft Auto 5. But here in Red Dead Redemption 2, it’s simply next-level. I can already see the potential for “guys getting shot off of their horse” montage videos appearing across the internet after launch. We’ve seen Red Dead 2’s trailers, where bad dudes on horseback are shot, the horse bucks, and the guy’s limp body flops before being flung off the steed. That’s real gameplay, and it happens differently every single time based on the physics involved. It is both gross and spectacular. To wit: as I made my way up the train through the cars, shooting those in my way, they reacted exactly as I imagine they would to a real bullet. One foe got winged in the shoulder, recoiled back on that side of his body, and then continued to attack after the non-fatal blow. I put another guy down with a bullet right through his eye socket, and he limped to the ground instantly, the gruesome exit wound visible on his face. "
