The PC Gamer Top 100 finishes today with the top 25 games on their list

We're happy to make an exception to our 'one game from a series' rule for Half-Life, not least because the original is so vastly different to HL2. This was a genuine milestone, marking the beginning of the modern age of PC gaming... and it's still an absolute blast.
Ross says "This was reviewed in pretty much my first week on PCG. It had come in just before deadline and there was no cover art, so we'd made this incredible, weirdly glowing lambda symbol out of nothing. I thought every week would be like that. Sigh."
GTA, but with sharper suits and better hats. At the core of this story-driven action game is a plot with real substance; around this the city of Lost Heaven revolves with its glorious streets, buildings and cars.
Tony says "The sweeping score of the intro sequence rushed me past a rocky coastline and into a beautiful, bustling city full of trams, period cars, hustles and dreams. 'Pah,' I thought, 'I'd like to see the game that could live up to even half this much ambition and sense of cinema.' Mafia lived up to all of it."
23 City of Heroes
It seems to undervalue this superhero MMO to say that its character creation system is its best feature, but... it is. It has far more flexibility than any other game's. You make your crime-fighter look exactly how you want, then head into the city to beat up bad guys.
Tom says "The confluence of coloured light and kapows when even two or three heroes bash goons together is spectacular. Better still, everyone has a different combination of powers, so no one's redundant in any group. Even your lowbie friends."
22 Company of Heroes
Was WWII really so good we have to go there again? Somehow, CoH transcends all that, turbo-boosting its vision of RTS with the need to continually attack, shift focus, react, conquer. Occasionally exhausting, the modern RTS doesn't get much better than this.
Tim says "It still cracks me up just how violent CoH battles can be. There are moments, as severed limbs roll down slopes, when you wonder how we get away with inflicting so much harm on imaginary little men."
With the passage of time, we make allowances for technical aspects that seem outdated or clunky by today's standards. Look beyond Fallout's façade - in particular the turn-based, tile-based combat - and you'll find a gem of an RPG, oozing atmosphere, strong characters, a vivid and unforgettable setting, and lashings of dark humour.
Ross says "Fallout manages to tug on your heartstrings with just a little text and a horrid isometric view. Most fantasy RPGs are too clichéd for me to become involved in emotionally, but Fallout is just so complete and convincing it's impossible not to be."
20 System Shock 2
Oh, did we say that Alien vs Predator was scary? Forget it. This is where to look for the real spine-chilling stuff. Still shining through the '90s visuals, Looking Glass's finest moment reeks of paranoia and blood. Aboard a sentient spaceship gone mad, SS2 gets all gory and then all clever-clever by turns.
Craig says "I doubt we'll see the like again. BioShock was more interesting than scary, and while the Thief games are disturbing, there's been nothing that's touched the sheer sustained terror of System Shock 2. It's not about monsters in closets or gore, although it has both: it's about sounds and claustrophobia and creeping evil."
