Try as they might, Microsoft has never been a big seller in Japan when it comes to their Xbox line of consoles. From the original system up to the recent Xbox Series X and Xbox Series S, they sell terribly compared to the other big competitors like Sony and Nintendo.

And they have certainly tried many times over, from getting exclusive games on their systems to getting new controllers to better fit Japanese hands. It should come as no surprise then to learn that some of these attempts never left Japan. Maybe some day they will come to the West. After all, Metal Wolf Chaos did after fifteen years.

7 Dennou Taisen: DroneZ

Dennou Taisen: DroneZ launched for the Xbox on April 22, 2004 . It was developed by Zetha GameZ and published by Metro 3D. Zetha GameZ seems to have a small presence online in the West and Metro 3D is also a small publisher, but some may have heard about their work on Dark Angel: Vampire Apocalypse on PS2, Armada on Dreamcast, or their Aero the Acro-Bat Game Boy Advance ports. In any case players create a male or female avatar and become trapped in this VR shooter.

6 Magi Death Fight: Mahou Gakuen

Magi Death Fight: Mahou Gakuen launched for the Xbox on June 4, 2002. It was developed and published by Takuyo who is a developer with not a lot of online presence. The game can be played alone or with a friend in co-op. It’s a top down arena fighter mixed a little with a puzzle game. There aren’t many videos of it online so it’s hard to grasp more than that.

5 ExaSkeleton

ExaSkeleton launched for the Xbox on December 18, 2003. It was developed and published by Kiki Co. This is a mech based shooter that doesn’t seem to offer much to the genre in terms of new ideas. The funniest and or most interesting thing about it is that it takes place in 2022. Unfortunately, mechs seem a bit further off than that in reality.

Aquaplus is known for niche RPGs including the Utawarerumono, Tears to Tiara, and To Heart series of RPGs. This game then is an action RPG starring a young girl. Based on the gameplay and art style, Tenerezza looks like the PS1 action RPG from Squaresoft, Brave Fencer Musashi.

2 Nobunaga No Yabou: Ranseiki

Nobunaga no Yabou: Ranseiki launched for the Xbox on February 22, 2002. It was developed and published by Koei. Not many releases in this franchise that began in 1983 have crossed over to the West. It is similar to Samurai Warriors, but if that was crossed with something like Civilization.

It’s also been awhile since the last release at all in 2017 via Nobunaga’s Ambition: Taishi. Knowing its legacy, this simulation game is probably far from being completely done.
