Tokyo Game Show - waiting time

Hi,

I'll bring my brother and his friends in the Tokyo Game Show on Sunday and I would like to know, in general, how long do we wait until enter. We can be there about 9AM and I know TGS doors open at 10AM and we expect to buy tickets in advance.

In fact, I have a meeting in Tokyo at 1PM and I just want to know if I can plan to go inside or not, even if it is just for a couple of hours (I'm not a crazy video gamer so does not matter if I don't stay long).

Thanks

If you get there at 9am, you may have to wait for 60 to 90 min, even considering opening may be 30 min earlier.

Tickets are already being sold.
Buy your tickets in advance at any convenience store.

Late September can be still hot, so don't forget any sunshade, drink, etc.

Does anyone know if TGS ticket sell out? Or is it okay to wait until buying tickets?

I went to TGS in 2006 around 11AM or so. I bought my tickets there, and I didn't have to wait. It was great :D

Oops, it's mid October this year.
