@Lord Soth: Congratulations on finishing DM!
I really enjoyed reading your adventure logs, and I still envy you for playing this game without already knowing it by heart. I think the best thing you can do now if you are craving for more is playing Chaos Strikes Back. You have already been warned that the game is BRUTAL. The beginning of it is much more difficult than the end of DM, and it gets worse from there. The most difficult part is finding yourself around. It's extremely non-linear, so if you are stuck somewhere, you can usually go back and try your luck elsewhere - if you can find the way back, that is. It's a marvel of cool puzzles and evil traps, but the feeling is very different than that from playing DM.
Forget about DM2. It's mediocre at best. Lots of custom dungeons out there are better than it.
About custom dungeons: The RTC dungeons I like most are these:
- Surgical Strike. Needs an older version of RTC (I think 0.36 or 0.37). It's somewhat similar to CSB in that you have powerful characters from the beginning, and the dungeon is rather non-linear. Features a lot of really cool stuff that seem impossible in DM (like melee weapons that let you attack from the back row).
- Sukumvit's Labyrinth. A bit chaotic at first, but crammed with nice puzzles and fights. Also quite a nice story that unfolds during the game.
- Tower of Champions. I have only scratched the surface of this monster. It's gigantic, very puzzle-heavy, lots of plot. May be even harder than CSB.
- The Two Lovers. A rather small and relatively easy dungeon that has some neat ideas executed well.
- Dark Portal. A pure puzzle dungeon that doesn't even feel remotely like DM. It's extremely amazing for the craft alone, as most puzzles require solutions that won't work in normal DM.
Finally, I feel the need for a shameless plug and promote my own dungeon Doom Blade.
It's rather large, semi-linear and features lots of plot.
Should CSB turn out to be too frustrating, I'd recommend The Two Lovers or Sukumvit's Labyrinth (or Doom Blade) first.
