WWE SmackDown! vs. RAW 2006 is very much a Yuke's PlayStation 2 wrestling game. That is to say, if you played any of the developer's earlier games, this one isn't going to throw you for a loop. What it will do is show you a number of key refinements to the gameplay that help it emulate real-life wrestling (we use the term loosely, of course) better than any game before. For one thing, SmackDown! vs. RAW 2006 introduces a measure of ring psychology to the proceedings. Don't worry; you don't have to plan your spots or your finishes or anything. What's been introduced here is a pair of systems that track your wrestler's stamina, as well as his or her momentum, in the match. Stamina drains a number of ways, though mostly through pulling off and being on the butt end of big moves. Momentum is built by playing a more interesting match, one that will get the crowd thoroughly behind your wrestler.
