I used to play strategy games. Got bored. Now I play first-person shooters. One of my favorite game is Serious Sam 2, although it's getting a bit dated now.

Choose a Level of Difficulty:

1. Tourist
2. Easy
3. Normal
4. Hard
5. Suicide
6. Are You Serious?!

At "Normal" level I don't even lift my finger off the trigger. It's continuous fire all the way man, and it takes days to finish this game. How much ammo is that? You'd need a microphone to record all the 'bangs' and 'reverberating' rat-tat-tats, then some kind of program to analyze the wave file. But only a computer can count that high. No human could solve that problem.
