I personally love my Wild Kingdom. Fun sounds and interactive. I think if you find a game that doesn't seem too repetitive, you got a winner.
Twin Rifle is awesome though because you have the two players....and shooting the duck is pretty awesome! I like the the pepper ghost illusion on these games, like that shoot out...when the guy goes across the scene with the mirror...awesome! What's the name of that game with the ninjas flying around....not a common manufacture of games? Also very cool!
Good luck with your search!
P.S. And on the projectile games with the real pellets...not a big fan! Suckers are heavy and huge! Also bullets tend to jam up occasionally and compressors are loud. I like the upright games much better.
