How many players/teams? :/

I cant say on her behalf but we had a poll at asiafortress and most ppl wanted 8 teams for the lan

Can confirm looking at 8 teams

Oh dear I forgot to add that we're looking at 8 teams. Sorry!

8 teams!

why 12 hours only? why not make it a whole weekend event?

It could still be made in 12 hours but it will be a really tight schedule for a double elim tourney I reckon

I'd say that if you want double elim, you won't be able to do bo3 through the whole thing, especially if you don't have enough computers to run 4 matches simultaneously. It'll take you most of the day to just get through the first round. Might be better off doing a single map for each round if you want double elim.

You can do a bo3 with that many teams within 12 hours if you use the Euro rule set.

Even that is stretching it. 14 matches, 30 minutes per map, call it 5 minutes between maps (that's cutting it close), and 15 minutes between matches. If every match is 2-0 you're at 1:20 per match, or 18:40. Run three matches at a time and you're already over half of the allotted time, not accounting for being unable to run 3 matches at all times because of bracket contraints, not accounting for matches that aren't 2-0, and not accounting for technical problems and other things that need to be built into the schedule (lunch comes to mind).

I don't see any way to get through a bo3 double-elim tournament in 12 hours unless you're the most efficient group of people on earth.

I agree with what everyone has said. Is there any other tournament format that I haven't looked at but should?
I don't want to do a BO1 because it wouldn't be fair, even though it'd fit into my time frame

Because it's expensive for the event to run throughout a weekend. Tight budget: funded by students mostly

you could easily fit a bo3 single elim tournament in. Perhaps run just 2 matches at once and keep a third set of 12 computers free for pugs or something so eliminated players can still have something to do.

edit: even one official match at a time would give you plenty of time in a single elim. That'd create some interest for every match because you'd have spectators for all of the action rather than one exciting match and one that doesn't have as many viewers.

edit again: never mind, you'd wanna run 2 at once for sure for the early rounds.

I think a bo3 pug rules game would work: first to 5 or 30 minutes with a golden cap if it's tied.

edit: but ya if you wanna be safe just do a bo1 double elimination.

I like what owl said. TFTV zowie #1 was 8 teams double elim bo1 with a bo3 finals and we finished it in 5-6 hrs. you can make more of the later rounds bo3 to extend the length. make sure to run as many games simultaneously as you can.
