The 10 Best Game Engines of This Generation
Without guts, there can be no glory: from Anvil to Unreal.

Australia, July 15, 2009 - Webster's Dictionary defines a 'game engine' as 'the word you've entered isn't in the dictionary,' but if it were to define it, it would probably explain that a game engine is used as the overall architecture to develop and run a game – it gives developers tools to create the disparate elements of a videogame and then pull them together to create a functioning whole. From the renderer to the physics system, sound architecture, scripting, AI and networking, game engines either natively power every aspect of a game, or they allow other specialised middleware to slot into the game's framework. In any case, game engines are the workhorses of modern videogame development.
Pretty neat article.
