Omni Link blends an epic visual novel story with real-time gameplay. The gameplay is also unique on it's own. You'll absorb and pilot ships with different abilities and can even use these ships as allies in a A.I controlled fleet for epic battles. You transform into them on the fly. It's awesome!
As a fully realized space game (inspired by Star Control 3 & Escape Velocity Nova), it also retains what makes visual novels great. A 20 hour story, romance, interesting characters, hand drawn characters and backgrounds, and choices that make a difference.
