For international audiences, Virtua Fighter 5 Final Showdown was likely the biggest news from Sega's booth at the AOU arcade show. But the company had a number of other new titles on display as well.

Sengoku Taisen

Likely to be the biggest title for Sega's bottom line was Sengoku Taisen, a new card game along the lines of Sangokushi Taisen. Sangokushi Taisen producer Yasuhiro Nishiyama is actually serving as producer on Sengoku. During a stage event, he revealed that the new game has been in the planning for over three years.

Nishiyama didn't say much about Sengoku Taisen. However, he hinted at some new technology. Joining the screen card reader that powers other card games, the game will have a voice recognition system. You'll be able to shout "Fire" to have your cannons fire, or "Attack" to make your troops attack.

Sega will be drafting famous authors for the game's scenario. Nishiyama also joked that all the various areas of the game, from cards to promotions, have a big enough budget to cause some voices of concern in Sega's upper management.

Sengoku Taisen is not a replacement for Sangokushi Taisen. Nishiyama also announced that Sega has started looking into creating the next version of that series.

Let's Go Island

Also reserved for video was the latest entry in Sega's "Let's Go" series of attraction-style shooters. The new title is called "Let's Go Island: Lost on the Island of Spice" and features a sea theme, complete with giant sea creatures. Operation date is TBA.

Borderbreak 1.5

This one isn't exactly new. Sega had the latest version of Borderbreak on video display. Not Borderbreak 2, though. The new version, "Borderbreak 1.5," adds new maps, weapons, equipment, and Blast Runner mechs.

Sega also has some big plans for BB.net, a mobile service that connects with Borderbreak and allows players to customize their mechs online. Valkyria Chronicles 2 character elements will soon be accessible in the game. The service will also see a variety of updates, including strengthened security.

Project Diva

The biggest playable title in the Sega booth was Project Diva Arcade. You can read Ryan's impressions here.

The arcade version of Project Diva appears to be pretty similar to the PSP version, down to the visual presentation and even the PlayStation family button icons. Icons move around Hatsune Miku, and you simply tap the corresponding button to the beat.

There are some new gameplay additions for the arcade version. In addition to an "Extreme" high difficulty mode, you'll find new Hold Marker and Simultaneous Press Marker elements. When the hold marker appears below an icon, you can press and hold down the corresponding button for high score. The Simultaneous Press Marker sees a line connect a group of icons. You have to press all the corresponding buttons simultaneously.

Sega refers to the arcade version as a "CGM (Consumer Generated Media) Rhythm Game." The game features music from the PSP version, but also adds user-created songs from Nico Nico Video. Currently, the title has just five such songs, but Sega says songs will continually be added to the game over time.

One of the main components of the PSP version of the game was the ability to customize your Hatsune Miku. You'll be able to customize your character by purchasing modules with points that you save up on your IC card or cell phone (your cell phone will need to be e-Wallet compatible). You can build up massive points by gambling your points on special challenges.

Project Diva Arcade has already appeared on location test. A full release is set for early Summer.
