First addicting game.

[MadMax]

I certainly remember playing the pong game and loving that, and later loving the games on the Vic 20, but the games that really had me addicted, were probably Cannon Fodder(Addicted to the theme song I think), Kick Off and Barbarian("Prepare to Die") on the Amiga 500.

Myst was the first PC game I really got hooked on.

3D load runner Atari 2600. I had Pong first, but it wasnt as addicting like Load Runner was. LD was the first time I felt like I was on an actual digital adventure within my TV screen. Hours would go by in the blink of an eye on such a simple platformer. Very few games bring me into that plateau, but I keep searching for 'em
