Seems there is quite the effort being made in the modding community of ROR to get us back to the "stone age", or the original AoERoR game experience - I am thankful for this, because I certainly like to play ROR that way too. A mod changing the buildings to their originals is currently being made, for example.
If you are a fan of Stephen Rippy's amazing musical creations (I certainly am!), you can now listen to the original AoERoR soundtrack in ROR by going to the in-game mods section and search for [RoR] Original Music (CD Order), which was just released by FE member StepS. I was the very first player to subscribe to the mod - thank you
