I have some other entries for the list.
v2 - eldritch05 - You Only Live Thrice
v2 - eldritch05 - The Guy Who Mugged Me
Both of these were HoV contest entries I created with my step-brother. If I recall correctly, You Only Live Thrice's system was exceedingly simplistic. The Guy Who Mugged Me's system was somewhat more complex and correspondingly more buggy.
v3 - eldritch05 - Epic of Serinor
v3 - eldritch05 - Epic of Serinor: Legacy of Llygam
The Epic of Serinor game from the early 2000's used a fully turn-based system as opposed to Dawnshadow's more active system. (I've since added an "Age of Heroes" subtitle onto the old game/story in my notes to distinguish it from all the other Serinor stories I have.) Legacy of Llygam was another HoV entry (I think? It was some time-limited contest, because it was released unfinished.) and uses a Might and Magic first-person sort of system.
