ALSO WHERE IS LOTR RPG!
too many zombie rpg's, a lord of the rings one would be sick.
A lord of the rings RPG would be pretty damn cool, but it'd either be just a small section of Middle Earth or it would be annoyingly lacking in detail.
I suppose you could always try something like the overworld in Lego Lord of the Rings, where Middle Earth (or at least ME as present in the films), is compressed into a smaller location.
So, from the top of Gondor you can see Osgiliath and Minas Morgul, but also Edoras, Isengard, Helms Deep and Fangorn Forest.
They're all just down the road from each other (despite being tens or hundreds of miles from each other in reality), but the individual locations are pretty detailed in areas. (Like, Isengard is pretty damn small, but Orthanc is closer to it's actual size).
If you could get a lot of people together to build it to a nice scale, and get some custom weapons and vehicles (Needs Wargs, Ponies and Oliphants), then it could be so much fun.
What would actually be cool on a much smaller scale is if some of the major battle locations of Middle Earth were constructed in detail, and then used individually as hosts for some themed TDMs.
Places like Pellenor Fields, Helms Deep, sections of Gondo and Osgiliath and Moria would be cool.
If you've played Lord of the Rings: Conquest (a relatively poor, but incredibly unintentionally funny game), then you'd get an idea for what I'm thinking.
You could take a leaf out of it's books too and include places where there weren't any actual big battles, like Fangorn, Internal Moria, Rivendell, Lothlorien and more.
If you did a few of these you could then set up a Gamemode with save rotation, like Speedkart maps.
