In the past i'ver owned all of the previous smash bros games, i had the first one when i was about 8 and loved it. Then when melee came out on the Cube i was officially house bound, trying to unlock all the characters, trophies ect was the most time-consuming thing in my childhood! Then when i bought a wii i had to get brawl.
However, after completing most of it (its extremaly hard to complete 100% it'll take you weeks of swearing and repeatedly clicking 'retry') i felt it was lacking somthing. It seems that with cramming all the new stages, characters and game modes (btw create a map is hopeless, i havnt created 1 map its so boring and the maps you create are pants) nintendo have left out the magic that was oh so present in the previous titles.
Another point is that snake, makes the game seem really far fetched, i no its not a serious game but the other new characters (sonic, wolf, king dedede) fit in really well with the smash bros world, wereas snake stands out like a saw thumb.
All in all a really solid and playable game which will keep you occupied for hours, but for me, a bit of a let down.
