I have always chosen the Stealth/Sniper option in any video game that allows them. I would never consider Fallout 3 a "stealth" game, but it's offers the option and it completely works to my play style.
Games have come from the "run-away" stealth and entered a more predatory version of themselves (MGS4, Arkham, Splintercell). It's nice to have a game that I don't have to restart every time I'm spotted (hey, I never said I was GOOD at these games).
So long as the game has a clear narritive, a solid design and a good direction, the blending of generas doesn't have to be a bad thing. Although, I would pay thru the teeth for a HD remake of Deadly Shadows.
