World of Warcraft
 

"What does Blizzard Entertainment do when titles such as Warcraft 1, 2 and
3 become increasingly popular with each incarnation? Mix one part MMORPG
style with one part successful RTS franchise and you get World of
Warcraft. The game is played like any other MMORPG out there with the
clichés of click, hit, kill, gain experience points and level up. In terms
of graphics, Blizzard has been true to their franchise, following the same
“cartoon” style used in other Warcraft products. So what makes this game
so appealing to the gamers outside of Blizzard’s realm?"
