TGS discusses the best game engines in the business.
"Any gamer knows that the heart of a great game is a well made and powerful game engine. It is the beast that gives life to our favorite past time and takes us places we will never see or experience in real life. Whether you want to walk on walls, see through buildings, explore an alien world, dodge bullets, run over a pink convertible in a diesel truck or kill four zombies with one grenade, it is a game's engine that allows us to digitally master these stunts without actually risking our lives."
