Mario Kart 7, I thought that was already guessed, but guess not.

Then MK8 is #15.

Finally someone got it, thanks. Were it the spell-names you remembered, or some other hint. Or the combination of them all.

It was a combination of hint 6 and 7.  I don't think I could get it based on the spell names, since I haven't played the series since #1 and #2, way back in the day.

Hmm, yes. As this wasn't be guessed, I gave with hint 5 and 6 the name of the game, and with hint 7 the genre, platform and hinting the dev. So with hint 8 I named something specific for the game. I dunno if any other game in the series used the same spell-names (the first Wizardries seemingly had different names).

14. Metal Gear Solid 2. I loved the boss battles in this game, and the story too. The Tanker mission was very excellent, probably one of the best starts to a video video game ever. This is one of the games I think that has gotten better with time with the War on Terror that has happened since, and the repeal of net neutrality.

Hint for #13: A game that revitalized a genre.

Final Fantasy XV?

Super Mario World

Really? I thought this would have been in a second. Well then;

#14 - Hint 2

What if I told you it has something to do with barrels, but not really.

As correctly guessed by John19 my game #16 is Kid Icarus: Uprising.

Masahiro Sakurai is a genius in game design and this game is another testament to that ability. This was a bit of a surprise for me. I'm not too big into shooters and if I'm more into classical western shooters than the arcadey shooters, but this was simply so much fun.

The gameplay was working very well, but what really made it awesome was the great level design, the silly story and the endless comments of characters of all sorts in this game. Explained simply with that the angel can hear the gods and their servants talking, the game was filled with chatter with all sorts of guys, including the bad guys you just were going to defeat in this level.

The game is crammed with content. The adjustable difficulty with rewards depending on the chosen difficulty make replayability of the levels high. The seemingly endless amount of weapons make this even more great. Add to this the great implemented achievements (I wish many games would copy this system instead of simly putting a list of achievements) for more enjoyment. And a multiplayer mode. All this additional to the already extensive main storyline. This made the 3DS so much more valuable.

And following the storyline. Each level was distinctive, the bosses were interesting, the twist interesting. The "Sorry to keep you waiting." I cited was the first text and was a mention of how long ago the last Kid Icarus game happened (remember, that was even longer for the japanese people, as Myth and Monsters never reached Japan until on Virtual Console).

This game gave me many hours of enjoyment. If you own the 3DS and haven't tried this game yet, should give it a go.
