Stand-Up Arcade Games
From Homestar Runner Wiki
As he has shown in many cases, Strong Bad has an affinity for stand up arcade games. In the short Arcade Game, strong bad gets a Trogdor stand up game, which he uses to "do The Cheat's taxes." You can play the game by reaching it from the Games menu, or from the end of the short. The machine can also be found in the DVD, where you choose your bonus material.
Also, in the email: "the bet", Strong Bad finds himself face to face with Typing Tutor Turbo. At first, he finds he dislikes it, but soon finds a use for it.
Also, the Scrolling shooter games menu itself is based on everal different arcade games. It has powerups, a fake score, and is even made by Videlectrix.
