Hi Holis
I’m glad you raised this point, as I am keen to address it…
I believe that the only real similarity between PKR and Stacks is the “3D poker”, however we do not like to use the term “3D” but prefer “immersive”; at PKR you can completely customise your own character and use poker tells and emotions/poker tells so that it is as close to a real game as possible online.
A great deal more information can be found at http://www.pkr.com and when this is compared to Stacks I think the difference is clear.
