User blog comment:Callofduty4/Why is it a sin for Treyarch to rip some aspects off of Infinity Ward but OK for Infinity Ward to rip off some stuff from Treyarch?/@comment-1651748-20091224002523

The revive system is basically the same for all war games. Pretty much there's a big button, you hit it and hold it and something happens. Just like in Army of Two. 1st one is possible, but very unlikely

Can;t say about waves, I didn't know Treyarch did anything in waves with zombies, but Infinity Ward completely re-did it, so I don't agree on the second one. I disagree on the second one.

Maybe on the second one, they added a little bit more to it, like the designs and the new two triggers. A little bit on the last one.

But Treyarch made WAW the same as MW, just with old guns and new charachters on multi-player. You have to agree though that Tryarch has ripped off a lot more from it's rival then Infinity Ward has.

I get what you're saying but each IW game is fresh and new with little tie backs. ACT just copies a lot of it off and adds some new guns and bam they have a new game.

Infinity Ward wins vote.
