You moron, HalfLife was probably the single best FPS that ever graced the PC in it's time. It had a great story, intense action, cool scripted events, and was voted best PC game of all time many times by almost every publisher and gamer.
Thanks for the insults. You act like I've slapped your mother.
HL1 IS boring. Great premise, but the levels themselves are terrible. Any part with the Marines was classic, especially using their equipment to call in bombing runs. But the actual progression through the game is tedious and uninteresting, beginning with the appearance of the first jumping puzzle, and they never quite go away. I maintain to this day that jumping puzzles have no place in an FPS. I think it was around On A Rail that I was asking myself, "What the hell am I doing?" The game's narration is completely lacking--constant reminders to find the Lambda complex is not what I call incentive to hop barrels floating in radioactive water. And, one word: Xen. Whoever thought up the design of that place is hopefully nowhere near the Valve premises now.
HL1 did have some great areas, like the section with the gigantic worm-like aliens that respond to sound. The first hour or so is extremely engaging. And of course, the Marines and Assassins are classic.
As for HL2, it looks like Valve threw out what didn't work in HL1, and ran with the environment and narrative. Combat looks fun, the enemies seem to be pretty smart, and that hoverboat chase scene is going to be amazing. Definitely looking forward to this, but you can keep your HL: Source.
