well I'm allso working on a map right now, and it's an island in the sea and I'm going to use the biggest ground part possible, letting it face the outside of the arena so the non-textured part is just like an invisible wall around the arena so escaping won't be a problem, and it allso won't spoil the eyecandy (wich is more important than in race imo), oh and please people, avoid z-fight
