The first computer game that ever hooked me was Raven and ID software's "Heretic, Shadow of the Serpent Riders". So, of course I had to get the sequel that followed called "Hexen".
In Hexen, you could chose to play as a Fighter, a Mage or a Cleric (mixed). As you may have guessed, I picked the Cleric. Each category had to find the peices of their final "Uber-Weapon". The Cleric class had a trident staff that shot out ghosts who screamed around, flying through doors and walls and generally killing any enemies they found nearby.
Looking back on it, the class was way overpowered, but I liked it at the time, so when I registered for my first forum, I dropped back to my old Hexen class. Been using it ever since.
