I hate the number thing. It is a good way to make clear it's the newest game.

Halo: COMBAT EVOLVED. Remember?

7, ok screw it.

but 8 is the perfect name for this mario kart.

the 8 comes from the format of a track that only is possible to run in it with anti-gravity. this format of surface is known as moebius strip, and it have lots of mathematical proprieties, among them, it only have 1 side(the inside and outside are the same side), perfect for a racing track.

Subtitles have been used pretty much forever and now that we're getting to bigger numbers (greater than three), it's starting to look strange to have numbers as well.

Mario Kart 8 says no.

I don't mind as long, as they don't go up to 5. At that point It's just overboard to me.

This is the third main halo game with a subtitle. Combat Evolved and Reach.

I think they could have easily clled it Mario Kart U and been fine, but agree the 8 and moebius strip did work out, the game looks great.

Resident Evil 7

I still like how Bravely Default did it- the sequel is Bravely Second, and both names are gameplay mechanics :D
