   3d max. xls or zbrush
  Im starting to study game art production, and i dont know which one is better to study to start my career. Which should i go for?   
  I would recommend you start with blender :) it's a great packet and it's free :)If you have a lot of money, then I recommend 3DS max or Maya.Zbrush isn't the right tool for starting as it require quit some knowledge.but that's just my opinion :P;  Learn to get really, really good at box modeling with Maya, Max, Blender, whatever. Zbrush is something you use to create detailed normal maps for your characters, not for producing actual character models. You can tell when people don't kbnow what they're doing when you see a model in someone's reel for "games" and the model is this half a million poly beat they created in Zbrush or Mudbox.
