The SvR2006 grappling system is often cited as the perfect balance between the arcade chaos of Here Comes The Pain and the simulation pacing of SvR 2007 . The momentum meter, the location-specific damage, and the stamina system were refined in 2006. Modern mods attempt to replicate the visuals of today, but they do so on a gameplay engine that is widely considered faster, more responsive, and more "fun" than the animation-priority heavy engines of the 2K series.
