From Playstation's perspective (I'll try to do the others later on):
To Nintendo fans: You should definitely try games like Ratchet & Clan. Graphics are cartoony, colorful and simplistic for the most part, so you should feel right at home.
To XBox fan: You should try God of War. Those games have as many lines of dialogue and as much testosterone as the Gears game, so you will feel right at home.
To PC fans: You definitely need to try The Order 1886. Since it's basically an interactive tech demo similar to the ones you purchase on PC to boast about graphics. You'll feel right at home with this game, which is all graphics with barely any gameplay value.
I am jocking here, in case it wasn't obvious enough. Don't crucify me. I'm only going from the stereotypes perspective. =P
