There have been four campaigns set in the Gwelith world: The Dark Knight, Revenge, The Dead of Winter and Underworld.
The Dark Knight and Revenge were both run using the Rolemaster RPG, but The Dead of Winter and Underworld are being run using the D&D 3.5 rules. While we (DM and players) miss the adaptability of Rolemaster, the D20 rules are so much easier to learn and play. The most noticeable difference being combat - a combat with 20 PCs nd NPCs would take hours in Rolemaster but a few tens of minutes in D&D.
