Too many to name all-time, but just for this gen my most overrated would be a tie between three different Wii titles (and I paid full retail price for all three) -- WarioWare: Smooth Moves, Super Paper Mario and Super Smash Bros Brawl.
WWSM: I guess I don't "get it." Mini-games. Outside of possibly the first Rabbids title on the Wii (which I did enjoy), this mini-game schlock is all mindless tripe with virtually no replay value. How a collection of three second micro games gets an aggregate GameRanking score of 82%, making it the 14th best game on the Wii, is beyond me. If this were $9.99 on a clearance end cap at my local Target, I still wouldn't buy it. To say I'm freaking ashamed I paid full retail when it came out because of the glowing reviews would be an understatement. One of the micro games should include taking the Wii remote and whacking yourself in the head with it for being stupid enough to play this "game" for more than ten minutes if you're over eight years old.
SPM: I love me some platforming. Mario too? Awesome. So shut up already! Enough with the damn talking! 15 minutes of reading unskippable text to stomp on Koopas for 3 minutes, only to be postponed by another 15 minute cut scene that can't be bypassed, fast forwarded, or whathaveyou. Made worse by the fact that the plot/storyline was childish and terrible. "BLECK!"
SSBB: I used to think multi-player fighting games were really cool ... back in 1995. Meh.
As for NOT being overrated, I'll vote LittleBigPlanet. I've owned it a week, completed it, played it online, and I'm going to go ahead and put it out there that this is the best title this gen, for all platforms. Heck, at 95% it's underrated. On a scale of 1 to 10, LBP goes to 11.
