Get the Tiberium Dawn mug.
The most fuck up game ever in the Tiberium series. From the most experienced series into the most stupid series. Many of Tiberium Wars die hard fans has throw the DVD into the trash can after the first time playing its campaign or skirmish mode.
C&C Fan : Dude ! Do you have the brand new release Command & Conquer 4 : Tiberium Twilight ?

Ex-C&C Fan : Yeah, in the trash can. You can have it if you want. But i doubt you will ever find a good place to put it after you play it.
