Empire is the SAME as Party with different multi-table tourneys.
Dante, you should consider it another door into Party. Entering a home presents a good analogy..Party is the front door and Empire is the back door.
Most of my play is through Empire due to other benefits that I receive which are not offered by Party. However, I do toss in at least 200 hours/month at Party to get a bonus and occasionally play in a big Mulit-table tourney there.
I'm sure you are not thinking this but if the scammers are...you cannot sit at the same table using both IDs.
Additionally, from what I have read elsewhere, Party is restricting players to one account on either site. There are folks who are grandfathered since the accounts were opened at both sites before they instituted the rule. Apparently, there are ways around this.
If you want to chat more, send me a note backchannel (czechraizenospam@yahoo.com)and I'll give you the information I have or point you in the right direction.
