Sword and sorcery is the basis of fantasy world, a world filled with magic. In these world, sword were no longer the only tools of war. Anything can be a weapon, as long as it is imbued with magic or runes. It involves powerful artifacts or hero that defies law of physics. The law of physics no longer apply as a hero could do almost all sorts of unexplainable things, such as levitation, or a huge massive sword conjured that could wipe an entire fleet.
This is indeed a very popular theme with superheroes to be seen. Sword represents weaponry and in such world, weapon differs greatly, in fact even a yo-yo could be a weapon. Sorcery represents magic, magic is often related to unique powers of either destruction or recovery. It requires chanting, or some with incredible concentration could cast it almost instantly as they have already chanted it inside their mind.
Sword also represents a warrior, those who go in the frontline, taking all the attacks and countering them. While sorcery represents a mage, an artillery that requires safety from all harm in order to complete their casting and unleash massive energy. However, you can blend these two together, creating a magic warrior. Magical warriors are basically a jack of all trades, however by harnessing magic in their fighting, it could bring huge advantage to the user.
Sword and sorcery without doubt, is the basis of al fantasy adventure games. A fantasy adventure game without one would be utherly boring, which is reality.
