When I think on what attracts me on wargames I believe feeling the climate of the game period is an important factor (and I guess this is true for majority of wargamers). Knowing that the theme of the game is based on reality, that all this struggle and drama actually has happened makes a good wargame an interesting experience for me.
From time to time I listen to music while I am playing, music which is related with the game. This sometimes can take the experience far beyond a gaming session and into the realm of thinking in the shoes of the leaders of the period and usually of one of the millions of other participants.
Below are a few favorites of mine. I tried to pick versions which usually have relevant videos. And of course thanks a lot for the original YouTube posters. I think some of them could be familiar to most of you and a few of them probably things you never heard of before.
I am not endorsing (or disapproving) any political/ideological ideas, which these songs could be related with :) It is just about the games, music and all the human drama associated with it. Just think that each and every person in these conflicts had their own dreams, desires, fears, virtues and weaknesses and I am sure you will enjoy your wargames better. And hopefully it can help us all to be more sensitive about present human suffering in several places on planet earth.
Axis & Allies Anniversary Edition
Triumph of Chaos
Clash of Monarchs
Here I Stand
I used to play Black Sabbath when we played axis and allies. My gameing friends used to listen to a lot of 80's metal when we played.
Any WW2 Eastern Front game needs to have Al Stewart's "ROADS TO MOSCOW" playing in the background. Amazing guitar work, and he paints some vivid images...
-- Two broken Tigers on fire in the night,
-- Flicker their soul's to the wind
G. Harding Warren
It used to be Steely Dan accompanying solo plays of Guns of August. No idea why.
I like the idea of Sabbath with Axis & Allies (or, Hitler's War, which I prefer), as suggested above.
