Snake was a terrible addition to Brawl, and easily the worst addition to the roster of any Smash Bros. game. The point of Smash Bros. is that it's a Nintendo fighter - In other words, only characters that are strongly tied to Nintendo or its hardware should be in the game. Solid Snake had three games on Nintendo consoles - Metal Gear on NES, a terrible port of an MSX game, Snake's Revenge, a non-canon game that nobody ever played or cared about, and Metal Gear Solid - The Twin Snakes, a port (that nobody cared about) of a game released the previous generation. Every other game Metal Gear game has either been Microsoft/Sony exclusive or Sony exclusive. Don't get me wrong, Pac-Man is an awful addition to Smash 4, but at least he's one of the most well-known characters in gaming.
