Tetris.
That´s all, no Top 5 needed.
Most casual & most core game ever, also most addictive and therefore most dangerous one. No one who played the game for the first time stopped after just 5 min and never tried again. Even devoted Pong fanboys switched to Tetris back in the days. I hide my Tetris DS cartridge from myself. This game started our neverending gaming hell of news tidbits, screenshot frenzy, sales discussions and its success is responsible for the existence of this very site. It should´ve been banned everywhere already in the late 80s, but the few governments who realized the danger coming from videogames just banned childish games instead, such as Doom. These fools. Tetris is one of the most favorite games of the owner of this site. Need I say more?
