4. Sega Rally 2 (1998)
Sega invented the bombastic race genre in the 1990s with Daytona USA, made it faster and more precise with Sega Rally, then added sexier visuals with Sega Rally 2. The key was how it managed the transition from loose gravel to grippy tarmac, a feeling no other racer captured so well.
3. Time Crisis (1995)
Arcade gun games blew up in the mid-’90s, when the 3D rush brought Sega’s Virtua Cop and the House of the Dead series. Namco's Time Crisis added a pedal to let players take cover, which brought a realism and depth of gameplay that had been missing from previous charge-through shooters. As a result it (or one of its sequels) is still one of the best ways to kill 20 minutes in a motorway service station.
Obviously you don't need to be told what Pac-Man is. The only way you could have avoided hearing about Pac-Man is if you're an 87-year-old judge who has assiduously avoided taking any interest in popular culture, or you're some sort of rare Arctic moose. If you're either of those things, welcome to a bewildering reality: people will spend billions (an estimated US$2.5bn in the first decade) on playing at being a small yellow cheeseperson who eats ghosts in the dark.
