Bought it for lore, inspiration and ideas how to play a game in the world of the Crow. You can tell the makers knew their Crow and the game is based on the first two movies. Because of this I give it five stars.

The big but here is that 5ed is a bad fit this kind of story, In the movies and in the comic a revenant has its power from the start and learns to use them quickly as in within hours if not less and after that they don't grow in power. A class/level based system such as 5ed doesn't reflect that.

It is based on Rolemaster but is using a D20 roll high system with exploding dice. It has borrowed some stuff from D&D but levels can go as high as lvl 50. Like D&D ability scores increases, in this case every second level but not after level 20. Character don't start superweak and don't become gods like in D&D, but there is more progress than what can seen in BRP based games, a newbie mage in Lightmaster has 20 Hitpoints, and archmage 120, the Famous Hero has like 180. As in Rolemaster criticals are very important in battles.

As for accesibility it is night and day compared to Rolemaster. It has a crystal clear layout, good use of examples that are not in the way. Not much art but very printer friendly if one want to hand the rules for character creation to the players for example, not to mention that the pdf is free.

It lacks ready made adventures but looking at the section for "Extras" will give you ideas how to adapt adventures made for other systems to Lightmaster easily.
