Half-Life is one of the best games ever and is still fully enjoyable seven years after it was released.
Gameplay: 10/10
Half-Life's gameplay really is the best part of the game and the part of the game that revolutionised the genre. The controls, the variety, the AI, and practically everything else about the gameplay are still great, even with the new fancy games out there. The game is still pretty challenging on easy, and normal and hard are extremely difficult at times. The little puzzles you have to solve make you feel smart when you figure them out.
Graphics: 10/10
If you have yet to buy Half-Life, you should buy the Platinum collection because it includes, among other titles, the Blue Shift expansion which includes a High-Def patch to upgrade the graphics in Half-Life, which were great in '98, but not too great now. With the HD upgrade, you have a game from '98 with graphics equivalent to a game from about 2002 or 2003, and even some games from 2004 in certain areas.
Sound: 10/10
The sound of Half-Life was top notch back when it was released, but it is still very difficult to understand some of the voices. Despite the voice problems, the music, gun clatter, and other sounds are very good and round out the experience.
Value: 10/10
Half-Life has a very good single player to keep you busy for a good time, excellent multiplayer, and a bunch of expansion packs to make the game last a very long time. Not to mention Half-Life 2, which you will want to play after playing the original game.
Tilt: 10/10
Half-Life is a revolutionary game that should not be missed. Half-Life 2 is also a revolutionary game that shouldn't be missed. You should try either one, depending on the speed of your computer.
