It's good, but anyone saying it's a replacement for the original, or better (other than graphically) is lying. I like some of the things it adds, but it completely messes up the pacing in many ways. Feels like playing a padded version of the original. Incredibly impressive and a fantastic fan project, but I don't like the narrative that it's a substitute for the original, or should be played before it. The only thing I can think of is if someone can't stand playing a game with old graphics so they gotta play this instead, but those people are scum of the earth and I have no respect for them.

A great companion for Half-Life, an impressive project, and a very cool reimagining. Definitely worth playing.
