I wasn't sure quite what to expect from Black Mesa, a fan created mod to recreate Half Life in it's sequel's more modern engine. The project has been long, and indeed still continues. A large group of people are even now continuing to create and refine the original Half-Life experience from the initial tram ride all the way to the interplanetary finale. Not to mention that now, as a standalone experience, you must pay to experience it, like Dear Ester or The Stanley Parable.
