That's a superb list of Vita games and many of them are titles that I play a ton, too. So weird that Duke Nukem got discontinued, remember playing it on Vita so wonder if I it's downloadable still? Full fat Borderlands 2 running on a handheld is impressive, even with all the bugs/stutters. But, yeah, Killzone Mercenary is the system seller imho. What an incredible looking game. Best FPS on handheld. Period.
