Ah come on, just go. Tokyo pisses me off, as well. But TGS is a different crowd. No brand whores or drunken salary men! Just a bunch of nerds there to get swag, support their fav developer, and play some demos.
One lesson I learned from last year was, not to go when it opens, because standing in the sun for an hour waiting to get in sucked and drained my enthusiasm. I'm thinking about grabbing an early lunch and then heading there.
If you don't want to go to there for the games, just go to hang out with some homies lol, but you would rather study then hang out with homies, right? If you're going to use a lame excuse like crowds prevent you from just comin' to hang out, don't complain about no one coming to your parties, bro.
PS: I will be going as random game enthusiast #4867
