Coming from someone who has used this application before -- I can assuredly say that it's not worth the $50 bucks it costs, including the $24 annual subscription that backs it, costing more than hosting a site for only a year...
For those curious, the tournament mod is set on a ladder and bracket function. It would be best for video games like Call of Duty where you can put in teams and then go head to head to see who wins. You place the groups in line, but the system is entirely buggy in doing so and there's no mod-help once you've wasted your money.
Inputting image data doesn't work the first time and has to be edited to get it to change, once it's set already. There's no size comparisons or examples for what to use, so you will spend 20 minutes trying to edit an image to fit for one type of combat or style of tournament.
It's clunky with it's wording and poorly, 'technically' written - to where trying to use the system is more of a headache than useful.
You have to have exact team numbers that are divisible by four. Four, eight, twelve, sixteen, etc -- otherwise, you can't have a tournament held at all. If you have seven people sign up, you have to kick out three of them because the tournament wont work otherwise.
Also, all of the values have to be hand-added instead of having a functional check-system, if you wanted to have thread battles or roleplaying combat.
All of this is to say that we didn't ever get a tournament off the ground because the mod didn't function properly in the end.
Hope that's a good enough review for those of you looking to blow 50 bucks.
