10) Inside (2016)
This modern indie classic conclusively proves that platformers aren't dead and buried just yet. Inside puts you in control of a small boy in a dark and harrowing world; solve puzzles and avoid the multiple deadly threats, and you'll progress towards the story's ending, which will linger in your mind for years after.
Inside is largely similar to Playdead's nearly-as-mesmerizing Limbo in approach, but throws in more curveballs and surprises along the way, plus it packs more of a punch as the storyline ultimately unfolds. Yes, it truly deserves to rank this high alongside the all-time greats.
9) Minecraft (2011)
Known to the still-unenlightened as "that block building game," Minecraft has captured the hearts of kids and grown-ups alike by proving every bit as big as their imaginations. It's LEGO writ as large as you want, and how it took humanity so long to come up with that simple idea remains a total mystery.
What makes it so special? Well its open-ended, open-world design lets you design your own fun with few limits, plunging you back into a time when you were small and had no worries about boring things like going to work and doing the shopping and getting a mortgage. Which is ironic, given that most people spend lots of time in Minecraft building themselves a house then searching for food.
Basically, it's the kind of game anyone can pick up and play and quickly lose hours to. Just try it.
8) Grand Theft Auto V (2013)
The best-selling game of 2017 so far is four years old. That is how popular Grand Theft Auto V has proven to be since we first saw Trevor curb-stomp a man to death by way of an introduction.
From UFO spotting to bank heists and family bonding, there is so much to do in the sprawling world of Los Santos that its map takes a full six hours to walk across. Or you could just stay put at home gambling your ill-gotten funds on the local property market. Add to this an epic, ever-expanding online multiplayer mode and you've got yourself a true modern classic.
7) Doom (1993)
Such is Doom's world-conquering prowess that there's a website dedicated to all the myriad platforms it'll run on. Apple's new Touch Bar? Of course. Your local hospital's ultrasound machine? Not the best use of NHS money, but sure. A toy chainsaw with a Raspberry Pi shoved into it? Nothing could be more appropriate for what is arguably the biggest milestone in PC gaming.
Doom pushed technology to the max with its 3D worlds and super-fast play, also introducing network code for link-up shooting battles. It was amazing. It still is. We'd happily play it today. In fact, we're going to play it today.
6) Portal 2 (2011)
We might get some flak from our dear readers for choosing Portal 2 over the now-iconic original, and in that case, fair enough: Portal was brilliantly inventive, impressively focused, and totally hilarious to boot.
But while the sequel lacked that same kind of singular impact, we'd argue that it was even better. Portal 2 saw Valve take the concept to new levels, packing in all sorts of new puzzle mechanics that all worked incredibly well, plus the new characters were great, the world-building was surprisingly enthralling, and the additional co-op mode was just as fantastic. Seriously, Portal 2: it's pretty incredible.
