Audiences don’t need to do anything other than pay a few more dollars and slip on a pair of special glasses to see 3-D versions of “Avatar” or “Alice in Wonderland.” For gamers, however, enjoying a 3-D game requires a bigger investment on their part.

We need to tell consumers about the wonderful experience that games are in 3-D.”

For many modern games, the leap to 3-D is actually just a step. The medium…
