5. Tekken: Dark Resurrection
Portable pugilists finally have something to be proud of in Tekken: Dark Resurrection. Fine-tuned mechanics make it the definitive handheld fighting game, not to mention the most visually impressive. Online bouts are missing, although head-to-head matches using any of the 30+ characters is an acceptable consolation. Niggles with the controls prevent it from being ideal, yet it's still the best example of handheld fighting given form factor issues.
