   What physics engine to use in an MDX game?
  I am currently planning/developing a 3D adventure game using Managed DirectX and I don´t know which physics library to use. ODE seems quite popular but does it have any decent wrappers for .NET?thanks!   
  Maybe this will help you:ODE.NET;  I haven't tried it myself, but you could take a look at Newton Physics .NET.  James Raine's solution might be a better solution for you though.
