Classic games?
shabda: http://www.miniclip.com/games/hangaroo/en/This was the game which got me hooked to programming as 
1. Seeing this game, it looked something cool .. and more importantly something which I can build. (If you played AOE, and thought you could build it .. more power to you.)
2. For some reason, I could just see how I could go about building it.I built it in pure Java, btw .. The source for it is lost, thankfully. (My first program, I didn't undersand arrays, and had code like char varA, varB .. varZ). The next game I built was probably better, and has the code http://code.google.com/p/spaceoddece/ and http://shabda8.tripod.com/java/Then I got a job .. left game programming ..moved to database/web development and Python. Hangaroo was how I started programming. Ah Hangaroo
