Golden saucer games

..., such as number of participants (must be an even number, because it is a 1v1 game after all...

Not necessarily, lets say there are 9 participants then you can make 3 Groups with 3 Player each and let them fight each other. So if Player one wins both battles, Player two wins against Player three and Player three losses everything that would mean Player one goes into the next Group (three People, one of each Group with the highest win /lose Ratio) and battle for first place in the same way.

maybe even two further three Player Groups for the other Players (just to get an Overall ranking or maybe even some (much lower) Prices like a few gil or golden saucer Points).

Then only Thing that would be needed would be something to do with draws (everyone winning once and osing once) for these cases there would be another way to evaluate how much your win/lose Counts (depending on the way how good you played, i don't remember the rules well enough to say how that could be done right now).
