I loved PKR, but the main reason for that was the players. It reminded me of
888. Soft field and a lot of recreational players. Probably the pomp around the 3D kept serious multi-tablers away. But the tourneys were great, soft and profitable.
I had a PC that could handle the 3D so I was golden, but these days probably most machines can handle it. If/when it is relaunched, I assume they will keep the grafix to a level that most machines can handle if they want to get back in the market. But I also assume the soft field will be gone, thus my motivation to play there may not return......
