The whole point of PHP is to avoid situations like this!

PHP is dynamic, you should have a database store of all your games, data on each game/movie would include the name, description and some kind of pointer to the file (like the file name of it or something) then when you load the page you fetch the data associated with that game from the database. Now you know the title and file name of the game, you can then use PHP to output HTML to reflect this. If you are hiring a coder and this is their intended plan of action I seriously recommend you find another coder, this is fairly standard practice and is why people use PHP to solve these problems.

Imagine if vBulletin made a page for each thread, that would be ridiculous! The only difficult bit would be the management on the actual flash & movie files, however I wouldn't consider it impossible.
