HOCUS

A 3d puzzle game based on impossible perspective and objects? Yes, please! Although Monument Valley  pioneered the concept of using impossible perspective in a game, it also sugar-coated it  and made it more about construction and the combination of pieces, the lovely designs and the music phrases that accompany movements across moving platforms, while Hocus focuses on the undilluted experience of enjoying the unsettleing and alluring  objects/drawings in the style of Duchamp, Escher, Penrose and McDonald. It's about consciously observing the geometry of each object while trying to find a way out for your red cube. The design is simple and effective , the controls are basic and levels progress with grace, each offering you the same exhilaration you felt when observing Escher's staircase drawing for the first time.

CARMAGEDDON

A relatively open world you can explore and demolish while driving in your car, racing against others or disregarding the track was a huge revelation for us back then. Sure , its elements were already present or implied in other racing and non-racing games, but it is the sum of these ideas and the presentation that made CARMAGEDDON a legendary game. It is gory, funny, replete with out-of-this-world characters and pimped vehicles with crazy add-ons that help you score destruction bonuses, Carmaggedon was a bold mainstream venture into the unknown that defied the racing genre and its narrow confines where  racing track was god. Finishing the race meant either clean racing , or destroying cars and property or killing all people in the streets.Sure, its outdated graphics might belittle its importance, but its pioneering  concept inspired hundreds of games in and outside racing genres, most important being the original GTA. Loads of fun , even today
Oh, and featuring Fear Factory's music in the game was the most natural thing to do at that time :)
