Eh
If I haven't already pointed emphatically enough at Darths and Droids1, allow me to do so now. It's essentially "the Star Wars movies as if they were someone's roleplaying game", and it's absolutely hilarious. You don't have to know anything much about either roleplaying or Star Wars to get the jokes, especially because the campaign starts from the assumption that, for these people, Star Wars doesn't exist; they're making it all up as they go along.
Anyway, I thought I might check out DM of the Rings, which was the inspiration for DnD. And frankly, it's vastly inferior. The DM's a total dick, the players aren't much better, the jokes aren't as funny and I find it offputting that you can tell what system they're using (D&D 3/3.5). It doesn't help that the story is vastly more compressed; DMotR is about 150 strips all told, for all three of Peter Jackson's films, while DnD is on strip #94 and hasn't even gotten through the pod race yet. Also, the word "jokes" is mildly misleading, in that it implies there are many of them; in reality there are...let me count...four: the DM is a railroading bastard and none of the players pay attention to his backstory for anything, Gandalf is an annoying uber-NPC, Aragorn is sex-obsessed, and Legolas just wants to kill stuff. With minor sidelines in "Gimili's been playing rpgs since rocks were soft" and "There isn't enough loot".
But I do love that they're playing a game that wouldn't have existed without Tolkein as if The Lord of the Rings didn't exist, it's pleasingly meta.
1: Firefox's spellchecker triggers on "droids", but not on "Darths". Odd.
