Now I'm not saying that they ripped it off or anything like that, I assume it's just a coincidence.
A few days ago I saw the Fortress Forever logo and it kinda reminded me to something I've seen before, in that moment I couldn't remember what, but I just found my Feindflug (an electronic music band) T-shirt and saw the logo, then all was clear for me.

So, this is the Fortress Forever logo:


and this is Feindflug logo:



Now, Feindflug is a WWII themed electronic band, wich shows heavy military resemblance. So what I'm trying to show here is how, with the passage of time, people has to be more creative and not just stick with the first idea that comes into your mind, wich in this case would be "military themed + 2 Fs on your band/game name = two Fs in a military logo style"


See what I did there?, created a serious blog out of nowhere.
