I loved the experience of playing on PKR.com, the Avatars and Table designs were beyond anything I have tried in the past and for me they were way ahead of any other site.
I was with them at the collapse, and thought I had lost everything I had built up from the 10 Cent giveaway games, I played and even won a few small Stake buy-ins, I had over £150 with them when they went broke and I thought it was all gone, Luckily Pokerstars came to the rescue and credited it to my Pokerstars account.
If it was re-launched with the same software I would certainly try it again, it was a lot of fun setting the mood of your avatar and getting it to say different phrase's at the table, sometimes insulting other players, but all in fun.
When the fun Stops, STOP!
