EVE Online and Pimsleur
Pimsleur makes the perfect companion to EVE Online, especially when you’re doing cargo runs or other things that don’t meed much concentration. Why not learn Spanish nipping out to buy that new Battleship? :P
I’m not sure if you can alter the in game music that EVE uses (and changing it to Pimsleur would probably be a hassle since you’re only going to play each track once) but you can run EVE in a window and therefore use whatever media player you like in the background.
EVE, EVE Online, Spanish, Pimsleur
