#50 An incredibly popular racing game that for the first time featured anti-gravity sections. Mario Kart 8 (guessed by Mnementh)

#49 Horse armour!
How has nobody got this yet? It's like the most infamous DLC of all time!

#48 Technically the 3rd game in the series, but also not a sequel. This time on a moon!
It added lasers to the huge arsenal of weapons that you could loot and shoot.

#47 This one is a sequel. It featured many different blade colours. It had the standard blue, red and green which were popularised by the movies. But also interesting ones such as orange and silver.
Had a morality system. One that actually ended up being a proper light vs dark one too.

#46 This entry in a long running franchise finally added a 4th playable kingdom. There are no longer just 3 kingdoms.
"Do not pursue Lu Bu!"

#45 Sony ruined this once awesome game.
The 1st of 2 MMOs based on this popular franchise.

#44 IMO one of the best FPS games on the PS3, and WAY better than its predecessor.
You went from the defender in the first game to the invader in this one.

#43 There were other great parts to this game, but to me the very best was all of the minigames. I just loved things like licking up sushi, splashing up and down, tossing snakes and so on.
Or hypnotising each other, hardening when rocks are fired at you, following a pink fairy's dance instructions etc.
