prono,
Saurkrat ( <-- spellin ),
ran an Aces High Dueling H2H Ladder for several years that was quiet successful here in Aces High
back in AH1 and during AH2, till eventually he had real life step up and get in his way, if I recall correctly
he also had a 2 vs 2 Ladder as well
with its own website and score tallying system, similar to what you have linked to above
TW9 was trying to get it going again a few years back, but I think Iraq came calling his name ( I may be wrong about the player and the fighting zone, just going off of memory here )
this was not an aces high ( HTC ) sanctioned event, it was done voluntarily by Saurkraut back then.......
if you want to do something like this try and see how many are interested in it, and if enough are ....... go for it, set one up....
hope this helps
TC
