A FEAST video game would be pretty cool. Nice siege-based gameplay. You would be stuck in the bar, have to barricade yourself in, and use improvised weapons (spear them with pool sticks, throw Molotov cocktails).

You could choose your character:

Bozo
Coach (Henry Rollins in pink sweats)
Beer Guy (Judah Friedlander)
Hot Wheels
Honey Pie
Tuffy
Bartender

And based on your character you would have different moves. Coach would break out into motivational speeches and Beer Guy would get high for motivation all the while your dilapidated bar is falling down.

It should support 4-person multi-play for more fun.

There can be different "stages" in the bar and then you can eventually break out, discover what the whole "government experiment" is all about (good GOD I can't wait for parts II and III).
