Games that shouldn't be possible on their system

[Despair]

Well, Radiant Silvergun shows off some great 3d effects, not thought possible on the Saturn. Very impressive.

SOTN on PSX shows off its 2d capabilities, that many thought that PSX was 2d disabled.

Sin and Punishment- N64
Yoshi's Island on SNES has insane graphics.

Maybe VOOT on the DC, it doesn't amaze until I watch a replay tough, no framerate drop and some of the areas are really spectacular.
Sometimes I can actually just sit down and watch replays and see the computer battle it out while eating chips, it can be like a good mech movie.

Adventures of Batman and Robin (Genesis)

Whenever I get to the first Two Face boss, I still look at my Genesis and wonder how the hell it can even handle this game.

[Clash!]

The game that knocked me on my ass the most was Super Mario 64. When I first got to see the game in motion at a Kiosk at Wal-Mart I almost shit my pants. I grabed that controller and went some where else, a place called the mushroom kingdom. It was so smooth and, looked like nothing else I had ever seen in my life. Sure I had seen 3D before on the PS, but nothing to this calibur and playability.

I was also blown away by Super Mario World. After playing NES for so many years, to finally see games I thought were only possible in the arcades also shook me.

Starfox for the SNES was like a bombshell when it was released. And the original Phantasy Star maxed out the Master System.

JSR and Shenmue for the DC also come to mind.

My original post went up in smoke when my frickin IE window closed for no reason. Here I go to the best of my memory:
Nes
battletoads
Ninja Gaiden 3
Castlevania 3
Little Samson
Batman return of the Joker
Swordmaster-bet no one remembers this one

Genesis
Batman and Robin-one impossible special effect after another
Alien Soldier-non stop multi jointed bosses that are fully animated? Yes please
Gunstar heroes-pure style
the immortal
Ranger X
Sonic 3 and Knuckles-such vibrant colors that shouldn't have been possible on genesis
Splatterhouse 3-Holy shit!
Vectorman 1 + 2

Snes
Donkey Kong Country 1 and 2-hate them because of the way they play, hate them because you don't like the graphical style, but no one can take away the fact that the graphics blew away anything else at the time. ANd 2 improved on every facet of 1.
Chronotrigger-both the spell effects and the music I didn't think possible on the snes, but there they were
Macross Scrambled valkyrie
Rockman and Forte-looked so much like 8, which I bet no one thought possible
Mortal Kombat 2-they really outdid themselves on this one.
Nosferatu-play it and see why
rendering Ranger
R-Type 3-shooter perfection on the snes
Castlevania 4-both the graphics and the music still stand up to later snes efforts
Super Street Figher 2-this conversion shocked the shit out of me.
Seiken densetsu 3-the only snes game to run in hi-res mode all the time and it shows
Tales of Phantasia and Star Ocean-the pinnacle of snes hand drawn graphics to me
Super turrican 2-Factor 5 know their shit
Star Fox-so what about the chip? It was still coming from your snes

Playstation
Soul Blade-even though it was on PS hardware, it still surprised me
Tobal 2-to me, still the pinnacle of PS graphics
Vagrant Story-ambitious as hell, but Square pulled it off on the PS and it shows
Valkyrie Profile-such insane hand drawn graphics on the PS nearly made me lose my mind
Castlevania SOTN-what can I say that you all don't know?
Final Fantasy 9-both the prerendered graphics and the battle graphics showed Square's mastery of the PS hardware

Saturn
Radiant Silvergun
Grandia-too bad we didn't get to see how it was meant to be played
Panzer Dragoon Saga-pure, 100% style
Virtua Fighter 2
Sonic R-that engine shouldn't have existed on saturn

Dreamcast
Soul Claibur-testament to the system that a first gen game still competes with some of the latest next gen stuff 3 years later
Shenmue 1 + 2-proof that the DC was as next gen as the other guys
Jet Grind radio-the one that started it all. You might not like it, but you have to respect what it created.
Resident Evil CV-Sega and Capcom outdid themselves on this one.
Red Dog-such an amazing engine and Argonaut said they had one twice as good.
I think the Snes did the best job of shattering everyone's expectations of what it could do. I await the inevitable flames.

Contra Hard Corps: Dead eye Joe running up the highway at you as you run towards the screen. Nothing like this was supposed to happen on the Genesis.

Sin and Punishment: Anyone who's played this knows. The level with the aircraft carriers while you fly around on a piece of the ship. I haven't seen anything on todays systems that can do to me what this one level on the N64 does. Amazing!

Batman and Robin: this game, like Contra HC is amazing to watch.

Definately, although I'm not sure if S&P impressed me with technical prowess or just the fact that it was so damned cool.
