GameTek

Background

1st Logo (September 1988-1991)
Visuals: On a black background, we see the connected letters "GameTek" appear in a stacked formation, with a sparkle shown inside the "a".

Variants:
 * On NES games developed by Rare, like the Wheel of Fortune and Jeopardy! series, and Double Dare, the logo is in purple.
 * Sometimes, the text is in one line.
 * On the arcade version of Wheel of Fortune, the logo is black and inside an circle.
 * On the NES version of Super Jeopardy!, the logo is on a purple gradient background, and the star spins.

Technique: None usually. Sprite-based animation in the variants.

Audio: None.

Availability: It's seen on several computer and NES games from the era, like the Wheel of Fortune and Jeopardy! series, as well as Classic Concentration, Harlem Globetrotters, and the NES versions of American Gladiators and Super Jeopardy!.

2nd Logo (1991-1998)
Visuals: We see the text "GAMETEK". A ball poses inside the "A" letter.

Variants:
 * The early version has a lighter color instead of  and seems to be a bit more leaned. The later version shows a solid 3D effect, including the ball.
 * On some published games, a corresponding announcer appears above.
 * On CyberBykes, the logo is redone in a futuristic font.
 * There is an animated version. It has "GAME" slide in, then "TEK" zoom letter-by-letter and the ball jumps the logo to take its place. The logo appears on some games from Imagitec Design.
 * On Star Crusader, the logo shares the screen with the Take-Two logo.
 * On Tesserae, the white background spreads around the small box with the logo.
 * On Wheel of Fortune Featuring Vanna White for the NES, the logo is in purple.
 * On games developed by Eurocom, like the 3DO version of Family Feud, the logo is shown on a spotlight that shines.
 * On the Nintendo 64 version of Wheel of Fortune and Jeopardy!, another animated version exists. The logo spins around and sparkles, and then a comet shines over the logo.

Technique: None. CGI in the animated versions.

Audio: None or the opening theme of the game.

Availability: Rather common on older games.
