Lord of the Rings (25mm)
In addition to Games Workshop, the official license holder to LOTR figures, there are a number of other resources suitable for both the skirmish and army games.
www.games-workshop.com: Main site, selling figures, rules and some terrain. A note on terrain: most of what they sell is Warhammer stuff, full of skulls and late Medieval/Renaissance crap which makes it unusable without conversion.
www.thomarillion.de: Probably the nicest 25-28mm terrain I have ever purchased. The sculpting is exquisitely detailed and the tone is very Tolkein-esque. I have purchased many of the pillars and statues for Moria.
