You mean time? Not really. Few games allow any movement backwards in time, and practically none have free interaction with this "fourth" dimension as they have with the other three.

Lots of games allow some movement backwards in time. They're called save points :)

Agreed, that's why I wrote free interaction, meaning the same kind of freedom you have in the other dimensions. Achron is the only concept I know of that has fairly free interaction with time. However, there are a number of games that have deeper interaction with time than just save games, consider the variety of games that now offer some sort of "rewind" feature of the kind pioneered (afaik) by Prince of Persia: Sands of Time.

If you want a game that allows more complicated movement in time, there is Achron (http://www.achrongame.com/site/).

There's also a 4th spatial dimension. The 4th dimension does not automatically equal time - it is only considered that when talking about "space-time".

also, check out Braid (braidgame.com) for a fun puzzle game that requires you to consider time travel.

Ken Kutaragi, ex CEO of SCEI, around 2006 declared the new Playstation 3 would be 4D.

I'm pretty sure he meant 4C - as in 4 C-bills.

Even that price estimate turned out to be optimistic.

I just landed and I can confirm that things are very bland here (and somewhat confusing).
