Two Factor Authentication is now available on BeyondUnreal Forums. To configure it, visit your Profile and look for the "Two Step Verification" option on the left side. We can send codes via email (may be slower) or you can set up any TOTP Authenticator app on your phone (Authy, Google Authenticator, etc) to deliver codes. It is highly recommended that you configure this to keep your account safe.
lines of code doesn't tell anything except the number of times the "enter" or "return" key was pressed.
depends, what do you mean with "size"?
size metrics for source code have only a useful relative meaning, but number of lines of file size is pretty much always a useless metric. Number of statements can be useful, memory size can be useful, compiled code size, etc. these can be useful

Nothing, it's just plain stupid to 'measure' a program. A program has to fullfill the tasks it's written for in the most efficient way possible. Like elmuerte said, lines could mean anything: empty spaces, redundant code, programmer notes, actual useful code, etc....
OTOH how what unit of measurement would be useful to measure the 'size' of a program ?
Lines of code ?
#number of classes or files used ?
...
While the number of lines of code in a program is certainly not an accurate representation of how much actual "code" is present, it does give someone who is unfamiliar with programming some sense of how much thought and work goes into creating a game engine such as UE3.
no it doesn't, there is no relation between required thought and the number of line of code that it resulted in.
also, previously invested thought time for old solutions is not shown because those lines of code have been replaced.

Also lines of code means nothing other than what elmuerte has stated, and gives the wrong impression of why code is complex.
Code:
for (i=0;i<j;++i) dothis();
Code:
for (i = 0; i < j; ++i)
{
dothis();
}
That part of the development-process is interesting indeed.
Imagine a program that needs 10,000 lines less code because someone found a better solution ...
I think there is no real way to indicate the complexity of code to anyone who is not familliar with the subject at hand.
// another example :
Code:
int addone(int i)
{
return i + 1;
}
main()
{
...
int i = 0;
int j = 10;
while (i < j)
{
doThis();
i = addOne(i);
}
...See ... I've added even more lines, the routine became even more complex (and has an increased chance of having bugs). It has not become 'better' code.

It is interesting to see what game-development tools are doing to 'traditional' Hollywood industry.

McCabe's Cyclomatic Complexity metric is quite a good indication of code complexity, and there are a few other good metrics when it comes to code complexity.
But code complexity is something very different from source code size metrics.

With the case in hand though a fair chunk of that can be assumed to be complex code and not just 'print' statements.
Everybody should know that assumptions are bad. Assumptions result in rockets blowing up, collapsing bridges, demoguy and darkpulse.
If they managed to get UE3 up and running just by using prints then hats off to them I say.
But your right you can't assume that its not. (though it almost certainly isn't
doing that is much more complicated than doing it the "normal" way.
ok, then show me a program that only uses `print' and can list the number of lines in a file.
remember, you can only use `print' in the source code, nothing else.
erm.. is there even a print function in C? ok, you can only use `printf'

I did say such a thing would be an insane way of coding.
Print "1"
Print "2"
...
I was trying to be nonspecific about language and used quotes to make it distinct from BASICs Print statement.
Edit..
Oops my bad. I misread your challenge. Nope I cannot come up with a version that would read another file.
More edit...
For something graphical you could conceivably come up with something by overlaying prints at the same x,y coords... aggh i'm starting to take this premise seriously.

There are tons of metrics. Usually they measure not so much the size of the program, but the complexity of its modules and its design. That is how many loops, checks, dependencies, etc. are present.

But as said, that's still not all that useful to compare any project to any other project.
