They were quite a bit richer. Looking at Ishar, Eye of the Beholder, Lands of Lore and Stonekeep.
New Dungeon Crawlers are just Dungeons, Enemies and Puzzles.
They are all more copies of Dungeon Master, but not of these "newer" generation of the early to mid 90s.
Check these games again. I am not saying that these were deep and complex games. But just check Lands of Lore and it's story. First you talk to the King, you run around in the castle, talking to the shop keepers. You go out charter a boat. You meet Scotia disguised as a young lady meet the Elf who shortly after that gets killed. It's all simple and rather simply made. But it is something exciting to discover.
Grimrock on the other hand. Whee…got a new text in my dream, found a new note…
You asked me for examples of games I felt did those things well, and I specifically pointed out that I couldn't make that true for you.
I can only talk about what I, personally, think and feel.
I don't need to check these game again. We're talking about some of my favorite games in what used to be my favorite genre. I know exactly how they play - and what content they have.
I gave you two examples and you've already admitted you haven't played them. Now you're saying old games were richer?
I don't know how that works, really.
I already said I didn't care much for Grimrock - so we agree it's not as good as the best of the old ones.
But in terms of features and exploration, it's very, very similar to Dungeon Master. In fact, someone re-created Dungeon Master almost exactly using the very same editor as the developers used for Grimrock.
As for Stonekeep, that's not what I would consider a standard blobber. For its time, it was a very expensive production - full of the trendy FMV videos of the time.
In that way, no indie blobber will be able to compete in terms of that sort of content.
But compared to Lands of Lore, for instance, Grimrock 2 easily matches that one in terms of exploration - and vastly exceeds it in terms of character mechanics and the combat system. It's quite diverse when it comes to environments, including dungeons, outdoor areas, underwater sections - and so forth. It's also full of neat stuff to find when exploring, including journals and more interesting puzzles than the prequel.
Vaporum is also very good in these ways, and it has stuff like audio journals - and a really good character system. In a way, it's more like System Shock combined with Dungeon Master - I suppose.
But, as with all things, it comes down to personal preferences. For instance, I don't think having a "shop keeper" is essential to my enjoyment of these games. I consider that a largely superfluous feature for the genre. To me, it's about dungeon exploration and immersing myself in an environment.
In fact, both Grimrock 2 and Vaporum COULD have shop keepers - I don't even remember.
Lands of Lore had voice acting for the CD version - and more elaborate story telling than Grimrock 2 - but in terms of the level design and actual gameplay/exploration - Grimrock 2 wins - hands down.
That said, I meant what I said originally. I'm not omnipotent. I can't take a modern indie blobber and make it give you the same experience - and I can't guarentee that it will have every single feature that YOU want in this genre.
All I can say is that I think both games compare very favorably to the games I mentioned, and I mean that - and I know what I'm talking about.
