I personally prefer WoW to Starcraft. I'm a sucker for the fantasy genre. Something about riding on the back of a dragon just gives me a nerdgasm.
Growing up I played the original Warcraft games and Starcraft. I think Blizzard loves me. Lol.
The diiferent wow is an mmo and starcraft is strategie like you howlight troops and tell them to go places , wow you sort of play as the character unless you mean warcraft which was before world of warcraft and is a real time strategie like star craft, I don't play starcraft yet I have both warcraft 3 (the strategie 1) and wow (the mmo 1) and am happy with them, warcraft 3 is the newest strategie 1 and is sorta a fantasy starcraft.
Warcraft if you prefer MMO's. Starcraft if not. I personally like Warcraft, the game play, the people, and the character development.
Both games are really really really ( and I don't think I can emphasize this enough) really amazing games. I don't know what there isnt to like about WOW and SC is my favorite strategy game of all time. Theres my opinion :).
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
