Round 5

Metal Gear

There have been few series which have expanded on their original vision quite so dramatically. Since its inception with Metal Gear, creator Hideo Kojima became obsessed with perfecting the stealth action genre, while fusing it with ever greater cinematic elements. By the time Metal Gear Solid dropped in 1998, Kojima's talent was clear to see. At that point, we'd truly never played anything like it. Dripping with atmosphere and full of neat little details, it didn't bother us one bit that we were spending hours staring at codec conversations. Kojima's penchant for the cinematic took increasingly outrageous steps, culminating in a 90-minute cutscene in the back half of Metal Gear Solid 4. Grab the popcorn, lads. Kojima's swan song for the series was 2015's Metal Gear Solid V: The Phantom Pain. A total reinvention, it added two huge open-worlds and totally dynamic gameplay into the mix.

Mario

The steely-eyed Italian plumber with a plan tops the list of the best-selling game franchises of all time. A constant in gaming during the past three decades, more than half a billion Mario games have been sold worldwide. Just to put that into perspective, that's 14 times more copies than Street Fighter, 70x more than the entire Max Payne series, and 106 times more than the Mafia trilogy. Despite being a familiar face, Nintendo constantly finds ways to reinvigorate the franchise, adding new mechanics, taking players to new worlds, and exploring heaps of genres. Next up - XCOM tactical strategy in Mario + Rabbids.

The actual list of games in the Mario franchise is a staggering 286 games long, so you'll have to forgive me for culling it down to the key titles below. That's still a formidable list, demonstrative of the 'tached plumber's enduring appeal.

Everquest

It can be very easy to run out of superlatives when talking about Everquest, but the footprint this early MMORPG has left on the gaming world is gargantuan. It was the world's first 3D MMO, and it paved the way for online co-op experiences as we know them today. Released in 1999, the original Everquest has had a staggering 23 expansion packs, including one as recently as November 2016. It's still played regularly by thousands today. Everquest 2 was seen as the dark sheep of the Everquest family, and it inevitably lost the battle against World of Warcraft, but Everquest 2 is still played to this day, with 12 expansions of its own. They're both hideously rough around the edges today, but they are some of the definitive embryonic MMORPG experience. Everquest 3 please?

Mass Effect

A series of towering highs and gurning lows, there's nothing quite so divisive as Mass Effect. BioWare's magnum opus, the Mass Effect series is the most ambitious sci-fi RPG ever made. A gripping plot strung the original trilogy together, BioWare mastering the gameplay elements with each successive outing. The ending of Mass Effect 3 may have got a few mouths frothing, but the trilogy has to go down as one of the greats. The less said about Mass Effect Andromeda, the better.

Series began: 2007

Best-selling game: Mass Effect 3 (6+ million)

Main series:

  • Mass Effect
  • Mass Effect 2
  • Mass Effect 3
  • Mass Effect: Andromeda
