And we could suffer some kind of explosion you know...

I'd say tokamak

Dreglor: ODE is a dynamics engine, say a physics engine. Collision engines are apart, a whole different world. Some physics engines has collision detection integrated, sometimes you'll want more than that. you'll need a collision engine then.
If you look carefully you'll find out a tokamak wrapper for blitzbasic then you'll be able to use it in purebasic for SURE. Later on theres ODE wrappers as well, some with real big nasty bugs... some others with no bugs, but they charge money FOR A WRAPPER (look at the world we live at...).
ANYWAY tokamak 1 was released for commercial usage since last year, as the team dropped it and started to work from scratch on version 2.
Enough said, I give my vote to any of those engines (trueaxis, tokamak, ode) I only got serious experience with the last two of them.
And yes, the developer of True Axis is very friendly and seems to fix most of the reported bugs.
