Unfortunately, to create a game you need quite good knowledge of writing code, and it has never fascinated me:) I know more about creating gameplay, level design, environment design, story telling, lighting, color grading, etc., i.e. more gameplay-visual aspects of the game, and that's not enough to create a game alone:)
The terrain textures are from Toon Fantasy Nature but I also used the normal map from FREE Slavic Medieval Environment to get a low poly effect on the terrain:)
