Thomas Was Alone, April
This makes the list for a number of reasons. Firstly the simplicity of its design is a thing of beauty. The amount of gameplay mechanics squeezed from a few different jump heights and shapes is staggering. Secondly the writing’s brilliant. They’re just blocks and yet somehow soaked in personality, with more life than some fully rendered people. The moment you find yourself rooting for a small square you know there’s some kind of magic going on. The third, final and most significant reason is that for many, myself included, this was the gateway game into the world of PlayStation indie stuff being a real destination filled with interesting content rather than some old tat knocked out by a no-name studio.
