There will be food. I think that's a given. I hope may Hotdog on a Stick. Convention staple naman siguro na sya. Ato sa Manila, mao man pud akoa gi suki-an.
There will also be a souvenir booth. If you want to buy Otaku memorabilia tha is.
There will be workshop booths. Just two though.
I'm not sure if there's a TCG tourney/booth. I think there will be.
I'm also not sure if may magbebenta ng mga anime merchandise since most anime themed shops na kinakausap are pretty snobbish and don't believe in the power of the conventions yet. We'll see in a few years.
Cospolitics - contraction of cosplay and politics
Cosplay - hobby of donning costumes; contraction of the words costume and play.
Politics - interactions of people with one another; most apparent if in the public sphere of life
I think that'll suffice for now.
You can buy wigs at Ayala and SM.
SM has more selection since SM has updated finally... I think they only update once or twice in a year. -_- Or if you're lucky and you know people online/from Manila, you can order from them too.
