I don't know why, but i don't see what people like about Halo? can someone who play Halo explain to me what's good about it?

i could continue trying.
Because that's one of the reason i never played Resistance or Killzone on PS3... since i dont like the unrealistic or future (wapons etc...) games, like the way you jump, weapons, when they shoot you (Halo and Resistance

)
But yeah back to the point, what's good about it? i try to play it, i just can't find it that "good"
