galactica.. I think its what its called, the most hypnotising music ever!
duck hunt
tecmo bowl
duke nukem
wolfenstein 3-D, though the graphics were very far from 3D
of course Mario Bros

I believe mine would also have to be wolfenstein, and I absolutely loved return to castle wolfenstein, its a great remake

Ooh, Contra t-shirts...I've actually never seen them. I'll have to look for them next time I'm in the States.

Check places like Hot Topic they have a lot of "Old School" shirts they have a tendency to be on the expensive side. I got Homer's Pin Pals bowling shirt there, I love it.

And I would also have to put in my vote to Leisure Suit Larry as one of my favorite old school games.

Double Dragon or Tecmo Super Bowl

ooh that reminded me of base wars. any game where you fight for a base is cool in my book

Super Techmo Bowl!!
Zelda
Punch Out
Castlevania (first one)
Bases Loaded

WORMS.. dont know if that counts

and raiden is super fun

Back when I was in elementary school, we had macs and a game called Dino Park was on it. It was a tycoon type game where you keep dinosaurs as pets and get people to visit them, kind of like a zoo. A bunch of us would constantly play it and get competitive on earning the most amount of money. Great game and it was quite addicting.

Zelda: Link to the Past & Super Mario Bros

They have T-SHIRTS?!? :eek:
I so have to get one now, Contra for the NES was fricken awesome! ^_^

Other great old-skool NES games:
Megaman 2-- The Metal Gun was simply the best gun any of the games in the series have ever had, proving the fact that the uglier the color of the new costume the cooler the gun. :D
Teenage Mutant Ninja Turtles II: The Arcade Game-- which was actually better in the arcades with 4 people, IMO.
Bible adventures-- I don't care what anyone else thinks, the Noah's Ark game was fun. Any game where you get to stun pigs with bales of hay, then balance them on top of your head, scores points in my book.

EXCITEBIKE!

That was a classic if there was ever one! I still remember hitting the buttons to groove to the beat at the end of levels [Unless my memory is failling me, which it often does...]

Others include:

NES: The Three Mario Games [1,2,3], The Mega Man Series [1 through 8 or 9], Zelda, Double Dragon and Duck hunt.

SNES:

Chrono Trigger
Final Fantasies [1,2,3]
Mega Man X, X2, X3 Earthbound
Terranigma (Not really well known) Secret of Mana 1 and 2
Secret of Evermore,
Illusion of Gaia
Sunset Riders
Aerofighters
Contra 3
Turtles in Time
Mario Cart
Actraiser [One Not Two]
and Super Mario World!

Hmm... From all these, I'd have to say Final Fantasy three would Just edge out the others for the number one spot.

Gothmog: I loved Starcontrol and Starcontrol 2! Brilliant games!

snes: Earthbound
...hmm...Earthbound was one of the strangest rpgs i had ever seen...the enemies were strange(crazed hippies, mean bag ladies, feeble old men, etc), and the battle items were weird(frying pans and baseball bats)...and the story line wasn't typical of an rpg either(i remember having to save a girl from the 'happy happist cult')...but it was one of the best rpgs i ever played.

I cant believe no one has said "Speedball" on the megadrive. I loved that game. I played it so much I burnt the cartridge out. If I knew where to buy it now I would. That was such a cool game.

Shining Force

Simply the greatest RPG ever. Ever. EVER!

double dragon... i remember a 15 minute wait minimum at the arcades when that game first came out. all the 7-11's had one and you could play all day an night. of course if you died, the person with their quarter up had next.
