Dawnguard is awesome, i beat it twice, first as the Dawnguard then as the vamipres, crossbows are badass but the power and freakin awesomness of the vampire lord is sick as hell. The soul cairn is creepy and lets you explore new places and encounter new and exciting enemies and a new horse, new dragon buddy and new shouts, new dragons, etc. Also, my stupid friend just burned his hand trying to make a sweedish torch, he put a little bit to much lighter fluid xD
