I remember when I bought my first Game Boy. 

I was already fighting a Tetris addiction at work (back in the days when the MS basic games were actually installed on the system by our IT section).  I could play Tetris for hours.  Then I bought Link's Awakening for the GB.  Loved it.

I have a later GB, and a lot of old games.  Haven't played them for years but I probably bought every version of Tetris there was and though I also bought more Link games, LA is my favourite.  I might get them out tonight.....and take a trip down memory lane.
