My brother gave me the shareware demo a week after I had broken my finger playing cricket. A few hours later I'd finished the demo, and my finger has never quite been the same.
I remember spending many Saturdays playing death match against my flatmate over a RS232 cable strung across the hallway. Taking breaks to hit the takeaways around the corner. That guy was in love with the plasma rifle, and he used it to beat the snot out of me more than a few times.
Now I'm the head of a computer science department and he's a funding director for a major research organisation. Coincidence?
