"It's weird to think of something that's only nine years old as "old school". But in our industry, five years is practically an historical epoch, as the way games look and play go through major evolutions in those short time frames. Visually, the Unreal franchise and the engine it spawned remain at the forefront of technological advancement. Of that there is no doubt.
But gameplay-wise, first person shooters – especially ones with a significant multiplayer component - have changed considerably over the years. Realism has become more in vogue, and along with things that go along with that like cover, destructible environments and vehicles. With the exception of the vehicles, Unreal Tournament III is definitely not one of those games. It's an old school shooter more closely related to Quake than Call of Duty 4, with fast-paced explosion heavy action, a sci-fi theme to the levels and the weapons and a bunch of fun powerups like shields and damage amplifiers. In other words, it's quintessentially an Unreal Tournament game."
