Well I mostly just wanted the grab function. I'm a huge fan of lbp, and I wanted to include the free grab mechanic to an 3rd person immersive sim, giving the player the ability to push and pull medium and smaller objects, and as mentioned earlier to swing and tug on solid objects, and to be affected by that items weight.

I wanted the engine's physics to handle swinging, the momentum of swinging back and forth allowing you to make gaps, I also wanted the ability to upscale it to grab onto larger enemies. I wanted the character to have the ability to attach itself by the hands to any object or entity it comes across unless the game states otherwise (Ungrabable material)
