It seems many Xbox gamers play more shooter games than other genres of games.
oddly enough this became apparent to me when I played GTA online on the xbox side…opponents were far more tactical and way more obsessed with their k/d ratios when I went up against other players in lobbies…on the playstation side, I was more likely to get into all-out brawls…just speaking in general but they didn’t seem to be as “skilled” as players on the xbox side
