Let's try:
First version 1.0.0. Played some gammas later on.
First PC Some sort barbarian, died from starvation in wilderness due to me not figuring out how to enter locations. After reading some manual orc Ranger did better due to survival still never made to anything but wilderness encounter due to same problem.
First artifact: Skullcrusher in Black market - few moments before learning shopkeepers are not pushover problem.
First legit win - orc priest. Did I mentioned I like orcs a lot in general?
First corruption - I think poison hands one. SurprisinglyI kept on for some time, guess mostly due to not knowing what to do with potions.
First thing eaten: kobold [second one rabid dog]. Killed desire to experiment with corpses for some time. Chars at that time was on strict orcs and rations diet. As I said I do like orcs a lot.
So far rolled 15 casters with RoDS and shamelessly killed them within 200 turns. For eternium glory!
(after 15 I stopped counting...)
