Poker Academy Hold'em Software

To anyone else that has this:

Do you think the computer improves when you move the game limits up?

I.E. do you think the NL XenBots play tougher if you play $500/$1000 than $5/$10?

Or are the limits just there to add some fun?

Where can you get the software?

you can get it at:

and several B&M stores.

I'm actually waiting for Negreanu's game "Stacked" which supposedly uses the same A.I. Comes out on 6/2/06 for $30 on all major gaming systems.

Looks like you can also get it free w/ a new account at PartyPoker by following the site link.
