Legend of Heroes (2000, Limenko)

LEAVE YOUR MARK ON HISTORY OF LEGENDARY HEROES!

Hmm. Standard fighting game, from the looks of it. Eastern martial arts combat, featuring a variety of characters of both genders, ranging from big to small, and each having a very distinct look to them. There's the shadow of a bad guy in the background.  I don't see anything really wrong with this poster...

...oh, wait. There it is.

Rolling Thunder 2 (1990, Namco)

I don't know if there's much I can say about this which could add to its awesomeness. The artwork is exquisite, while the text is shameful.

MISSION

DESTROY NEOGELDRA

THE EVIL ORGANIZATION !!

"ROLLING THUNDER" IS THE SECRET

AGENT OF WCPO

SUPER ACTION GAME

CODE NAME: LEILA ALBATROSS

I think if an evil conglomerate were to name themselves "Neogeldra", they'd automatically be assumed as Japanese. The main bad guy's name would be Parn (he looks like a businessman, but is actually an alien with two additional boss forms including one that is just floating eyeballs), and his associate/henchmen would be Vrad (Vampiric football star), Syliur (effeminate whip-wielding cyborg), Davis (the token black guy), and Laura (half-mermaid with a trident and half-Japanese).

Mind you, our hero's code name is "Rolling Thunder" which sounds like a dietary aid, and the code name of his mission is "Leila Albatross".

I really can't add to the awesomeness of this image.
