Ok, just gotta let me cook:
1. Load solid shot ammo in a tank
2. Put a marble in the barrel (a toebreaker), right in front of the round
3. Fire
4. Profit
It just looks so...right. There was also some goofy stuff like the Me 163, very lethal (to both, the enemy and the pilot/crew) but not so good looking.
I can see why that's a money pit! Now, if you absolutely hate your wallet, you can get into mountainbiking as well
Also, do you know the Messerschmitt Me 262? The most beautiful plane I've ever seen IMO...
