Many of the tutorials for medieval builds I have seen uses this texture. While some look nice, none have created this feel. The Skyrim one I thought would but then I got a look at the spruce wood planks that are simply horrific. The wood isnt that grand either, default pack has more realistic looking wood.
Anywho, please make a medieval themed texture pack that actually looks like something that would be in an RPG or medieval setting
The Fantasy Texture Pack seems to be a good one. I'd check that out if I were you, it's the closest thing to medieval and you may or may not like it, as it isn't totally realistic looking but it has some nice textures and the wood and stone textures are especially nice and on point.
I do have the Fantasy one as well (Halo, Skyrim, Fantasy, City and Steampunk) though there are things I abhor about that pack, doors being one (I know I am kind of strict when it comes to my builds)
Right now I am using the Skyrim, which is overall nice but have to make adjustments when looking at tutorials to learn (endstone for cobblestone, oak for spruce, etc). Most of the ones I have seen are the PC version which uses the Conquest/JS pack which seems flawless and would love that on the 360 version.
