Well, we could do something like simon says, lr fr, red light green light.
I'm only joking sniper.
I might have a few suggestions though, since I think this is a fantastic idea - brainstorming new games is always a plus in my books. So, we could try:
Dark Knight - This is for the map with the Roulette game built into it (unfortunately the name escapes me at present). For those who don't know, the roulette game is built so that there's a roulette table in the middle of a "room" (it's more like a small pit in the ground), with two gated cells on opposite walls. One is the "green" team and one is the "gray" team; roulette is then played, and wherever the ball lands, that team either lives or dies (depending on what the warden states beforehand). It's similar to couch game.
So, my idea is, we have everybody on both teams face the wall of their containment cell in roulette. Then, we select one person from each team to act as a representative for that team. The representatives will shift walk to the gate, and look out towards the roulette table. So, at this point, only one terrorist on either team will be looking at the roulette table, and everybody else will be facing the walls.
At this point, it will be explained that the representatives have two choices: They can either stay on their side, with their own team, or they can move to the other side, to the opposite team. They have a certain time limit to choose, and then they have to freeze.
Then, it'll be the team's turn to move. So, only shift walking
without turning around , they'll have to choose to either remain on their own side (in which case they don't move at all; the moment they initiate the movement, they must switch sides, or they die, as they can simply shift walk until they see if their teammate is next to their goal and then run back inside). So, to reiterate, the teams then decide if they want to switch to the other team or not. Then, they freeze.
Here's the catch. If both representatives are on the same side, then that team dies, and the representatives and the opposite team lives.
If the representatives are on opposite sides, then they compete between each other to determine who dies; and, whoever loses, their whole team dies.
The only drawback to this game is that it takes ~1 minute to explain properly. The compensation is that it results in a lot of terrorist deaths, so it evens out in the end.
I think this would be a really fun way to spice up roulette, since really, it's the same game, just played with a twist; it still involves an active choice by the terrorists (based on chance, but this isn't different from roulette anyways), so it's not their being killed based on a choice made by others. They simply have to hope to get lucky.
I'll post other ideas as I think of them. I'm glad to see that we're brainstorming!
