B, PVP. However, it has to be a skilled based game, and not something that's based on luck or at least have some skill, and some luck like a lot of the card games out there. This has been done though. I'm personally, against any completely luck based games, I just don't find them fun. You're basically guaranteed to lose in the long run. Hence, why I like sports betting. I see it as myself against the bookie that puts the odds out. I lose most of the time, but I still don't feel like I'm being cheated out of winning by some predetermined odds.
