I've Played Dungeon Crawl: Stone Soup for a couple hours and I'm not sure about it yet. It's very different from Nethack and I feel like I have fewer options in the early game. The game is simpler in a lot of ways. There's no hunger and you can't eat corpses for resistances, there's an auto-explore feature, you can't sell items, items don't have blessed/cursed status, you can't steal from shops, don't have to identify most items, can't polymorph items etc. etc. etc. However, I keep dying around dungeon level 4.
Part of the problem might be that the auto-explore and weak initial monsters promotes playing on autopilot until you run into something you can't kill, but I feel like I keep running into named monsters and don't really have many options against them. Once you are in combat you simply can't get away. Most monsters are as fast as you and running away gives them a free attack every turn, unlike Nethack where only faster monsters get free attacks. You can't just stay on higher floors and grind because there is no monster generation beyond the initial population, once you've finished a level, it's done. You don't have many potion/scroll options because you don't know what they do until identified and you can't do price identification in shops to make a reasonable guess. I don't know if the game intends for you to quaff random potions or what, because lacking the mass identification options that Nethack has I don't know what choice you really have. But my Nethack experience has taught me that using unidentified items is a bad idea, not only is there a chance you are going to use something bad for you, most of the time you are just wasting a potentially rare effect for the sole purpose of identification.
Surely there has to be options to you that don't rely so much on RNG, but I don't know what they are I think before I play again I'm going to have to read over the available documentation, and then maybe I'll see what the 'hints mode' has to tell me.
