I played about halfway through original half life before switching to Black Mesa and honestly it didn’t change how I felt that much. I get that it did a lot for the fps genre in terms of immersion and storytelling but it’s a slog to play through. It’s too long and you spend so much time in ugly, boring hallways and vents and miscellaneous factory shit. So much of this game could be trimmed. There were cool parts that I enjoyed but they weren’t enough to stop me dreading the next alien factory I’d have to trudge through.
