Ok, you may not got much from my question so here is some further information. (To all those who watch the show and know all the episodes!) There is this one episode where Sheldon is sitting at his desk and plays an old pc game. The concept of the game is that the game provides you some clues and you type the next steps. I think he was trying to kill something desperatelly and kept typing stuff. At the scene Leonard was at the back talking to him about something. Does anyone remember what the name of the game was? And does anyone know if it still exists? Thank you in advance!
