So other than that everything else is the exact same is what I am seeing? Withdrawal requirements and times promotions, etc all the same and no problems getting money out compared to Black Chip and ACR.
Yea like Evan said, from my understanding just a different skin with perhaps it's own bonus or promotions.
I do know that, as long as you don't play at the same time with 2 accounts, which is a clear violation, WPN (parent company) is fine with you having accounts on each skin.
The benefit here is that you can clear a first-time deposit bonus for each skin. Also, if there is a freeroll, you could enter the freeroll once under each skin.
If you don't care much about that stuff I'd recommend just playing on the main ACR skin b/c some of the other skins may not show all tournaments/games.
