If we're doing non-D&D, I'll put forward one of the many early-90s ICE modules for Shadowworld (statted for RM and Fantasy Hero): The Orgillion Horror
Going off a tangent here (in 2023):
Leafing through this module I must say I don't see it. The greatness, I mean.
The house is mostly empty (i.e. no encounters except random ghosts). The story basically amounts to plopping a Doppelganger into the adventure, and letting the GamesMaster figure something out. That is, isn't this just the kind of good old non-adventure adventure where all the work needs to be done by the GM, rather than, say, supplying an actual plot with listed encounters, colorful NPCs, and such?
(And the latter half of the adventure is just a crypt stuffed with a large amount of non-descript undead and some high-powered random loot)
I guess I don't see what value the written text adds over the basic premise.
While the layout of the manor is okay (especially given it is such an early/old module), there's basically nothing in 85% of the rooms.
Do you remember what you had in mind when you recommended this scenario twelve years ago? Do you have any thoughts on what I might be missing? Or is it simply "we had a great time, and I realize now that it was MY imagination and MY energy that made this great rather than anything the actual module supplied"?
Cheers
PS. To be honest, of what I've seen of RoleMaster/MERP adventure scenarios, it doesn't surprise me in the slightest that D&D won out and that there just isn't any choice if you want ready-made d100 scenarios. Almost all of ICEs attempts at writing actual scenarios (as opposed to supplying campaign worlds) fail miserably to me. Filling MERP module after MERP module with "here's a bear and there's some bandits; you can kill and loot them if you want" isn't exactly evocative of Tolkien's writings... Perhaps it could compete with early AD&D dreck, but it doesn't hold up today. (I thought I could run some d100 adventures with the Against the Darkmaster ruleset, but after looking around I'm basically baffled how hard it is to find even a single scenario of quality written for d100 games!)
