Hi Gamenut,
As far as I'm aware any computer purchased in the last 8 years or so have built-in 3D, even if they don't have a card dedicated to it. That being said, we're going to use an engine that's been proven to work on a very wide range of computers. However, if in the off chance your computer cannot do 3D at all, no, you would not be able to play the game I'm afraid.
