Its really a matter of opinion. Call of Duty requies a lot of skill, but Things like Halo 3 are more fun for lots of people (e.g. friends over your house), but don't need as much skill. That's my opinion.
yes but you have to connect cod waw to the internet and set system settings so you can go on anything then you can go online
Yes, there is online multiplayer on Call of Duty 4: Modern Warfare.
Unfortunately no, you can't play multiplayer on Call of Duty Modern Warfare 1 or on Call of Duty Modern Warfare 2 on the same screen. But on Call of Duty Modern Warfare 3 and Call of Duty Modern Warfare Black Ops you can play multiplayer on the same screen. There is an new Call of Duty Black Ops 2 coming out soon though, so I expect that to also have that feature, since its newer.
Call of Duty World at War, Modern Warfare, Modern Warfare 2, Black Ops, and Modern Warfare 3 all have online multiplayer.
