No doubt. I remember being younger and always wishing there was a game where you could sneak around and have a free roam map, as pretty much all games up until that point were more of the side scroll games where you went in the direction the game wanted you to. I thought it was the greatest game ever when it came out lol. But you're right, it's like the magic is gone after the first one.
I make my livin on corners by turnin n***az into organ donors, fuck diplomas.
The first Splinter Cell did, IMO
But yeah after that, it was very been there, done that. Stealthy gameplay has it's limits. What gamers really want is something that either makes you think your way through it or not think at all and just go guns blazing or swords swinging
