Call of Duty gamers and gamers in general

Taking into account multiplayer as well.

I kinda remember playing both, it jus depends on the person playing it. Ikno that doesn't help.

My only concern would be since those games are "old" if there would be anyone to play online with( if that's what you meant by multiplayer). I think both are two player (somewhere down t he line cod stop making it so two pple could play together not online).

Anyways watch some youtube videos and look at the guns and graphics and pick one.

Lol ikno I wasn't helpful, goodluck tho

Modern Warfare 2 has definitely earned a lasting reputation as one of the richest Call of Dutys, and its single-player campaign was somewhat of a game-changer for first person shooters in general. Overall, gameplay and story have held up pretty well, so if your sibling hasn't played it yet then I'd recommend it out of the two. As mentioned by someone else, they are both old-ish games, so multiplayer might be a bit less popular either way, but I've read that there are still a couple thousand people playing Modern Warfare 2 online due to its notoriety, so it has that going for it as well.
