I mean in shredsauce you can build a park with pre-built features. But you can arrange them in certain ways to make it super unique, like different rails (z railes, s rails, battleships, etc....). You can also put jumps and landings at different angles and positions to make different types of jumps like step downs and step ups.
also if your gonna get into shredsauce get a wired xbox or ps3 controller, it makes the games 1000x better.
