I'm one of the people who can study in absolute silence, but who prefers to study to a nice song or some background noise. My favourites are rain (and thunder), night sounds, Harry Potter ambients, and Plague Inc soundtracks. Don't ask me why.
One of the things I've always liked about Plague Inc. and its computer version (Evolved) is the music. It's fitting. Creepy. A little dark. Just perfect. And it's only €4,99. Alternatively, you could also look up the songs on youtube and throw them in a repeat list. But hey, €5 isn't that much. Why not support them? ;)
(No, I do not get any ka-ching for writing this. Sadly.)
Look what I found this Friday evening! I was looking for a Plague Inc-like game, and ta-da! This is Bio Inc. Your goal in this game is to kill off a single person using a disease which you control. The funny thing is that you can give this person a name of your choice! So if you really dislike someone, this is your chance to kill that person in your imagination/in game-form.
Plague Inc. I'd like to present Plague Inc. to you guys. It is an Android game, available for free in the Google Play Store/Android Market. It's also available in the iTunes store for Apple devices :) I've been told that it is similar to the Pandemic flash game, although I haven't tested it.
