Only PSP Poker games i could find were -
World Poker Tour
World Series of Poker
World Championship Poker 2
World Series of Poker: Tournament Champions
All of which feature characters of some sort. Sorry.

Totally agree, WSOP has the option of moving fast but that way you can't get a feel which player is tight and which is agressive.They all have to put stupid characters in which make a game boring as each move is so long.
