Some games impress by their simplicity, and make a long lasting impact on the industry as a result. Mini Metro is one such game.
It's now been ten years since the first steps of the indie hit, with developer Dinosaur Polo Club celebrating the anniversary next month with a big crossover update between Mini Metro and its similarly successful successor, Mini Motorways.
This is a big milestone for Dinosaur Polo Club co-founders, brothers Peter and Robert Curry. Celebrating ten years of Mini Metro was important to them because it's the "seed that formed the studio," as Robert puts it.
