I just read the Resistance 3 review on Eurogamer.net and read some of the comments about how the sp component of a game is more important than the mp...for me its true.
This made me think about me and my friend. Hes a mp kinda guy, and im more sp. A good example of this is when he bought FEAR 3 end of last month and i recently bought deus ex: Human revolution. We obviously not able to buy both...actually i can but just have zero interest in Fear 3 :P He couldnt though and im sure if he could he probably would have gotten deus ex as well, im sure hel get it soon anyways.
Point is he saw greater value in fear because of its mp, he has quite a bit of friends on hes psn list, and they told him its a fun mp so he got it. He tends to prefer a game with a mp component and if it doesnt have it then hes hesistant. Me on the other hand.....lets just say i wont buy a game solely for its mp but i will for sp (unless its Hon or dota etc.).
So, in general, which type is more important to you when choosing what to buy?
