organize a event not that easy though, you never look deep into it.
I briefly tell you some of it.

Wide Coverage obviously required Internet Connection
-This is where internet come in, required tmnet as sponsor, but on another side note, you need to pay rental fees also to management as using thier facilities, yea, ISP can give any free bandwidth boost just for few days event or even FOC for few days event, but who pay the facilities charges? (Sponsor Obviously)

Marshall
-where to choose a qualify marshall, who know the game well, and not prejudice yet fair, and dont forget, you need to pay marshall salary, if too low who wanna work? time management for marshall having shift for having breakfast, lunch and dinner?(obviously you all wanna having food with ur fren.) who would pay the salary which is rm100 to rm120 per day, where thier working hour might be 12 hours long?? and there is head marshall where higher pay. who gonna pay?( none, except they really generous since all organiser would like to save as much money as they could, they would more happy able to get volunteer,normally they would pay rm60-80 for marshall if they somehow agree with that salary.)

Sponsor all Grand final winners to Msia, dont think much, u just need to get samsung to pay for it, and organiser just need to get thier namelist, passport number, or even try spoke with embassy for country that required VISA to come here, and yet, booking for hotel room.
(in2 certainly cant make it, erm...manpower not enough probaly)

Commentator - sorry, there doesnt have good commentator with good english here, including me. best you able to get is (wah lau!fake)
Or get hit.fm crew which i sometimes feel like they disgrace our knowledge.

Goverment - might be morale support but not financial, what for i support your event when none of the msian able to get any champion or title at all, face the fact, goverment always like to see result in short time which same as us seeing goverment done all thing in efficient way.

Console gaming - you can find m$ to done thier xbox360 launching during opening or watever...big big prize...hot chiqs...great cash...and all won by foreigners...i meant for international events.

Banners and advertisment - you need to becareful on this part though, some sponsor, if they doesnt see thier banner clear enough, not at the good position...they would scream!!! at u! advertisment doesnt have thier company logo/name...they would complain u!! this will make you depress as they might threaten, we will not sponsor anymore..or maybe next year...hahaha..obviously all sponsor want to expose thier company logo/name as smart or most attractive as thier could, if not what for they sponsor the event.  this leave to organiser to decide.

Equiment rental - do you think renting the hall is cheap? mostly cost rm20k per day, LCD TV rental, cordless microphone rental (RM150/unit per day)
oh yea, time management too, you need to rush the time, which sometimes authority would charge rm1k-3k per hour, if u doesnt clear the event hall fast enough.

and yea..this just briefly...most important part is, organiser only receive thier money after 2 month - 1 year..the rest is they fork out thier own money except deposit which taken of course.

shit, i must be too crazy woke up 5am..

but telling you all, doing event is not easy, what i saying is just briefly, there is so many problem/troubles occur b4/during/after event.

Yeap, msia event organiser certainly better than singapore, but why AWCG doesnt host here?? i dunno..

obviously organising a small tiny event is easy, time wise doesnt need to bother much, a Grand event would make ur hair totally turn white though.
