Good point! He didn't do a basic research about his idea (many members here had the same idea, to create a PvP game, but more than that we never hear).
(....)
Let's hope OP that is not misunderstood the game he/she mentioned. Since maybe what he/she mean about player vs player is like a poker or some card games for example that is only for 1 versus 1.
On first glance, after I read the OP especially the title of the thread, it seems like a new level gambling especially it needs personal skills to play with it, not by pure luck. And for sure since OP mentioned "developer idea", it's the kinda techy part where it will be developed from the scratch.
