Many magazines have done this, but those are mostly editors choices. I would like for all to say a few games that shocked/amazed/make you laugh/cry, in short, rocked your world. What it was and if you found a vid or pic, post it!
So heres a few of mine:
Bad Fur Day: The great mighty poo
I even recorded the song because i found it Hilarious. Conquer's Bad Fur day has quite a few but this is the greates one IMO.
Final Fantasy VI (FF3 for SNES in USA): The Opera
Not only you HAVE to learn the correct lyrics in order to procede to the story, you have to move and play it! One of the best compositions in all FF games, totally unexpected also. The lyrics were re-arranged for FF6 advanced. I still like the original the most.
Metroid: Samus is a girl!
Whoever played the original NES Metroid, (before all the codes and ***) you wouldnt expect that your valiant character was a girl all the time!
Resident Evil 2: Mr.X is Back! Twice!
At 3:00, when youre lighting the flames and the gear fell, your like "Great :D" then just a walk and BAM!! that bad-*** mofo again. When I played this I almost ***myself.
Super Mario Kart: Rainbow Road Shortcut
If you never found (or was able to make) this shortcut, shame on you!! When you do it, your like 1/4 ahead in track.
And
The greatest moment in gaming history
no intro
Final Fantasy VII: Aeris Death
No moment in gaming history has ever make so many people cry like this one. I personally confess that I cried when I witness this.
Edit: Changed the Video, cuz the previous one song, was put over, this one, is the original as seen in game. The arrangement of the song was not need to be changed in my opinion.
This are the ones at the top of my head, Add yours!
