some suggestions

As previously stated, there\'s a large possiblity that we will write our own(which ultimately would be better overall anyways because TTR is online focused, so network friendly physics is a must)

As Joe stated, Havok is *far* out of our price range. I\'ve looked around alot at different physics engine solutions, and ODE while good overall, obliterates network performance without heavy tweaking on both ends of things. Novodex would be a good solution, except that we would need to support the physX chip, which no one on our team currently knows how to code for, let alone has the extra cash to get the dev kit i\'m sure would be required to use it.
I\'ve also looked at Tokomak, which suffers most of the same problems as ODE, and Newton physics, which while slighting more effecient on the networking, doesnt have as near robust a feature set as of yet as the other physics solutions.
And all of these(with the possible exception of novodex)are not geared towards networked physics.

If we coded our own, however, we could make that a top priority, and everything would be better in the long run of things.

As for your question on things like slings and the like, yes, we can implement that, and there\'s the probability that we might, be because we dont have a physics engine just yet, it\'s lower on our priority list
