or Gears of War Two Tech Demo.
The GoW2/unreal engine tech demo thingy was really cool. This hidden message highlights the arms race between Epic and... everyone else who makes 'for sale' game engines or middleware.
Similar to the Cold War, Epic (lets represent them with a randomly assigned country.... The USA) are building up their atomic arsenal in a bid to bully everyone else into doing what they want. There is some resistance however, from the likes of id software (Russia) with their Tech5 engine.
There are a few smaller players. Havok (represented by the UK) Have some form of nuclear detterent but as with most UK based stuff it's not a complete package and its a pain in the arse. NaturalMotion (erm, who can they be? Lets say Japan) with their Euphoria stuff are the new kids on the block, but they have much awesomeness going on.
But the USA, sorry, Epic will probably go on to become the big superpower in game engines.
Personally I'm looking forward to the new game using the Unreal Engine:
