I kind of like the candles rant, but it's otherwise pretty forgettable. Even 3 is only really famous for the first half of it with Vargas slowly losing his mind.

I always play them in three stages.

1. Sneak around with a bow and a knife.

2. Sneak around with what can be best described as a howitzer with a silencer.

3. Get bored and clear every remaining base with a ludicrously overpowered pile of solid gold machine guns.
