I sold my IMDN pro right away - - to buy an IMDN premium I liked the game so much.
I sold my DP pro after the latest code release - - and bought a Star Trek Premium.
DP Pro was a snoozefest for me and got to be really repetitive really quickly. Very few ways to really attack the game and the rules and game play just felt very uninspired and a lot left to be desired.
IMDN still amazes me.
