i don´t remember quite well but my first computer was only a dos prompt, you could only choose between the text editor prince of persia and a game where you were a fireman and had to save babies that came out of a building on fire,
When i got my 2º computer the babies jumped so fast that i was unable to save them =(
 i remember playing games like x-com sim city disciples of steel and so on...  and i didn´t have to work nor study also =P
