I was even amazed by the interior designs, like caves. They seemed a lot more naturalistic than the typical dungeon-style caves you find in other games.
I think it's a game for geeks... the visuals of the engine, the physics, the freedom to choose how to accomplish a goal. You could play the whole game over and try a different approach for each scenario.
I tend to think this type of engine is the future of FPS games. Gameplay tuning still needs work, but the advantages of huge environments where just about every object is interactive is too great to ignore.[ Parent ]
