Okay so I couldn't see a half-life thread anywhere, which kinda shocked me, due to the fact that it is a really high rated game.
I have been playing Half-Life since it's original release in 1998, I absolutely loved it, including it's three expansions packs (Opposing Force, Blue Shift, Decay).
Half-Life 2 blew me away with it's twist in story line, I felt like the most recent HL games (hl2, hl2e1, hl2e2) are almost like watching an interactive movie - there is no cut scenes, yet you still get a really good perspective as to what is going on around you.
The expansion of the HL world with games like Portal was just awesome, even though there was no significant link between the games, just the fact that they mention Black Mesa in the game was pretty cool.
I cannot wait until they finally release Half-Life 2 Episode 3.
To anyone who hasn't played any of the HL games, I really recommend you do. If you are keen to buy one of the games, start with "Half-Life: Source". It is a remake of the original game, but with the more modern engine - although it is not up to HL2 standards, you will get a better gaming experience if graphics mean a lot to you.
However, nothing will ever beat the original Half-Life.
