I initially hoped for a fun and unique experience when I started my Chaos Knight, especially since I just finished the game with a L+ character, but all I got was punishment and "can't do that" without anything really new. I think the Chaos Knight removes too much content out of the game without adding enough to make the class fun.

Want to do most quests in ADOM such as Dwarftown and Terinyo but also others for example the Weird Tome? Can't do that, you need to be neutral for that. There is also quests you cannot do even when neutral such as the Sheriff quests.
Want to get the Healing skill? Can't do that, you need to be neutral for that. Yes, even to kill Jharod.
Want to get food from the ratling traders? Can't do that, you need to be neutral.
Want to be neutral? Can't do that, you need fire resistance and a LOT of tedious sacrifices.
Want to use your class powers? Can't do that, you need to be chaotic for that.
Want to train your attributes by spending gold? (Garth) Can't do that, AT ALL.

I think it is also important to note that you're not really playing a Chaos Knight if you're not chaotic: First of all you're not evil which is kind of the point with the class, secondly you lose all your class powers which is like playing no class at all.
It is also common to keep re-rolling until you don't get horrible corruptions at the start: such as unholy aura, stiff muscles and Teleportation. Which is just another thing to add to the Not-fun-pile.

It's fine to make exclusive content for certain classes and races but everyone should have roughly the same amount of content. It doesn't need to be the same content, just the same amount of content, roughly. The game already has this to some extent, you can choose to help the sheriff or to kill him. You can choose to help the healer or to kill him. That's good, it makes repeating playthroughs different and fun.

You might say that Chaos Knights are suppose to be a hard class to play. Maybe. I don't have a problem with challenging races/classes but I MUCH rather play as a hurthling merchant than a chaos knight if I want a challenge since I can fully embrace the merchant class without missing half the game. I was going for Ultra Chaos God Ending with my Chaos Knight, everything was going fine, first kill farmer, pre-crown done, dwarf-shop sells a AoLS. Going pretty good, except one thing. It was not fun. So I'm not going to continue. I rather play my Ratling Fencer which I just love, THAT class is a unique and fun experience. No shields, only one-handed weapon, Massive focus on weapon skills but perhaps the most important: Still the same amount of content.



So there is a lot of solutions for this: You could have alternative quests and NPCs which let's you embrace the Chaos Knight class but still makes you feel like you didn't miss half the game. You can lessen the severe penalties for alignment shifts. You can let the Chaos Knight talk to more people. I don't know the best solution, I'd think I prefer alternative quests/NPCs, but I do know that the Chaos Knight needs roughly the same amount of content as the other classes. If this is the same old content or new content, I do not know, either is fine by me.
