Physics

So, I've just finished playing around with the Tokamak Game SDK, which is a physics and collision detection sdk. Man, it's easy and it's quick. However, the community seems dead, so that scares me and is making me hesitate about committing to it... Also, no source, So i can't port it over to an XBOX 360 if the oppurtinity should ever arrive. So I'm going to try out TrueAxis tonight. The only thing is, I have to pay for TrueAxis.

I have a decision to make. Commit to Tokamak, it does what I need it to and when AND IF, the oppurtunity to port to XBOX 360 arrises, I will change then. I will have to design my code to handle this situation. The Bridge Pattern comes to mind.... Or try out and commit to TrueAxis and possibly fork over alot of money if my game is succesful... hmmm... I think the first option seems more practical at this stage...
