Well, if it did make Halo dated, then Halo 3 wouldn't have sold as well as it did, now would it have?

Super Smash Bros Melee made every other fighting game look dated. Brawl blows them out of the water and into orbit.

Marvel vs Capcom is another good series that comes in second too brawl imo ....Powerstone on dreamcast also had a good 4player concept going .

Hey, I got the game. I still suck at fighting games although I enjoyed the side-scrolling platforming. Maybe I wasn't ready for the truth, or maybe you just got lucky. Your blind fanboy-like enthusiasm is legend.

Fighting games aren't disappearing because of Smash, they disappeared along with the arcades. Also what works for Smash Bros. wouldn't work for other fighting games. The reason Smash has that much music is because it's built around 25-30 previously released games and the music comes from them. The only fighters that should be compared to Smash Bros are licensed games and Final Fantasy Dissidia. If Street Fighter IV has 200 songs, who's going to care? If it has a stage editor why would anyone give a crap? Most fighting games work off a single plane anyways. Actually some fighting games have a feature that hasn't been in Smash yet, the character creator. Other games like Tekken, Mortal Kombat and Soul Calibur implemented adventure modes and minigames a while back in the series. Some games offer previous releases on them, like Virtua Fighter 4 offering Virtua Fighter 10th Anniversary Edition on it. Guilty Gear has a very extensive mission mode and an ass crazy story mode.

In fact, the only two fighting games that are a bit light on modes are King of Fighters and Street Fighter.  

yes, it has more depth than any other fighter

I think so, because it has some polish, some many features and so much content its hard to think of a fighter that is as good as Brawl. The only critiscm is the release date. Pity us in europe.

Smash is casual, and core.. That is why it has such universal appeal.

 Oh I was blind, but now I see!

 you mean except for ssbm.  ssbm is more polished in every way except the balance and AI.  although the multiplayer in brawl is more chaotic.
