Best games of all time on all platforms

This is an always difficult list to make. I've played a ton of games in my life, but some do stand out above everything else. The most troublesome is to be objective and not subjective. I'll try that.

Platform games

Easy.

- Super Mario series. Since Super Mario 64, Nintendo crafted what simply defines a platform game. I read eons ago an interview with Shigeru Miyamoto that they started the games by working on the Mario movement and controls and that's what it's all about. Fluidity and joy.

- Ori series. Microsoft did hit gold when they bought Moon Studios. Ori was built on the same principles as the Mario games and it shows. It's simply a joy to play these 2 beautiful games. Hope there's a third

- Rayman series. Some brilliance and originality along with great gameplay

Honorable mentions. Iconoclasts, Kirby's Epic Yarn, Fez, Celeste

LittleBigPlanet series (mostly 1 and 2) deserve a mention for truly fantastic and original ideas, lousy games, unfortunately. Rare's games from their golden age (Banjo's games, Donkey Kong Country, Knight Lore) are still quite good but have not aged that well. Psychonauts 2, seems very interesting, the first was good but not enough.

Racing/driving games

- Kart series, Nintendo. Simply the best and most fun, not pure racing but very well done brilliant gameplay and with decent AI

- Forza Horizon Series. Another Microsoft smart buy. These games are good and really enjoyable to play

Honorable mentions. Gran Turismo series, Blur (a game with half-decent and interesting AI, but plagued with other issues), Burnout Paradise (dumb but fun)

Shooter / Twin Stick shooters

- Geometry Wars series. Simplicity is sometimes the best approach, a fine example of this

- Dead Nation. Best Housemarque game by far.

- Assault Android Cactus

- Robotron: 2084. Yep, still that good, a simple concept but a really good one

- Ikaruga. A synonym with extreme difficulty

Honorable mentions. R-Type series. Alienation (could be the best of all, a true pity of too much RNG downgrading the game). Gradius series. Radiant Silvergun. DoDonPachi. Sine Mora.

FPS Action

- Horizon Zero Dawn. A decent story (not important but better than a bad one), interesting combat, and good enemies. As a whole miles away from all similar games anyway.

Games with no specific genre

Or that don't fall exactly into other categories

- Journey. Not exactly a game, but a really good experience

- No Mans Sky. A launch disaster that evolved into something awesome and unique. Best continued development of a game ever. Kudos to Sean Murray.

- Sandlot EDF series. A series of games like no other.

- Elite Dangerous. Be prepared for hundreds of hours of gameplay to be good at it
