Issues concerning the sample projects

I don't understand why just about every sample project you download is riddled with bugs.

Some people who try out a product would like to see it in action before they devote a good portion of their time to it. I know how to program in several languages but c# is not one of them so trying to resolve these errors is not something I know how to do right off the bat and frankly neither do most of the new comers.

I am using 5.3.5f1 Personal edition & Visual Studios 2015, if that is any help, could someone link me a working project it doesn't need to be anything fancy I would just like to see what Unity has to offer.
