You sure about that?

How do we know the last name of the Demoman isn't McTavish?  He has the accent to be a McTavish.

LOL. That's a game! Yeah, there are a handful of brothers all over the world, but the chance a brother is named McTavish? Oh wow. Haha!

Well, the Demoman said he is rare.  So, spread the rumor that his name is McTavish.  I WANT TO SEE IT GO VIRAL!

Anyhow, more proof there may be Scottish people of color (and McTavish):

We may also have a McTavish here.

And how about some Afro-Celt Sound System?

I have to take a different tack, and state that as the MW2 SP plot is essentially completely and totally implausible, silly and plain bad, any attempt to analyze it is essentially moot.  Take point 3) - its just plain silly.  Your position, the response, even the attack, make no sense and are driven by nothing even resembling exposition.  They just happen because that's what IW wanted.

It doesn't make sense, even in terms of its own imaginery Universe, and it exists not to be consistent or even convey a general combat areana, but simply to service a series of disconnected firefights IW felt you would like.

Forget the plot is my advice, mainly because there isn't really one, just the semblence of one - interesting point, Transformers 2 and MW2 have actually no real consistent plot and exist simply to service the disconnected events they contain that were constructed to appeal specifically to males of a certain age and inclination, and both are the biggest events of the year in their respective medium in terms of sales, particularly in the US but also to a surprisingly large extent outside the US in Europe : wonder what that bodes for the future of intelligent entertainment vs recycling franchises into increasingly unfocused gibberesh.

/ Rant over.

There is debate and discussion going on now, about games as a medium for telling stories. It is entirely possible that it will take a very rare breed to be able to integrate both together well. It is also possible that the two concepts work against each other.

A story is generally not interactive, with the storytelling forcing the listener/watcher to suspend control and follow, allowing to be captivated by the way is going on.

A game is a set of rules that govern an environment, and players try to manipulate the environment in order to accomplish goals.

You also have the play concept, where you drop players in sandboxes and they create their own goals, and change the environment to suit their whims. In the sandbox, it is hard to run narrative. Your focus is on creating a flexible enough sandbox the player ends up feeling that what they have is something worthwhile and engaging. For the person not engaged, without an internal drive, they will happen to not get into it all and wander aimlessly.

In all these, the goal is to captivate the consumer of the entertainment. All of which end up having a different ways of going about what they are doing. Businesswise though, we lump the last two, and the first (as interactive fiction) together under the broad category of "games". Even puzzle stuff is put here. Interactive fiction, games, and sandbox/toys/play areas are all considered "games".

@ Richard - haha. My great-grandmother is full-blooded Scottish! My dad's granny, but my name ain't McTavish. Still, I think he's my favorite character to play. He rawks.
