I have not seen game tournaments, a tournament for me is when people face each other, and they do not fight against a computer, or against a system, I have never been in tournaments that have the impression and communication with others, I think it is the most typical way to raise the adrenaline and with money, with poker I have not seen here but only against the computer and almost all casinos have poker games.
You've never been on a poker tournament that involves real people I guess mate. I don't think you're aware on the bitcointalk poker tournaments that was held by forum members here and if really not, you may check this recent one:
