The one, the only, the NightKawata!!!
I am the guy in charge of the Metanet Hunter lineup. We've got the GB-style Metanet Hunter/Metanet Hunter SE (play Metanet Hunter SE if you're interested, I would not recommend the first one), AND we've got the new Metanet Hunter CD launched up and rollin'. Get out of the way, Limp Bizkit, we're the ones rollin' rollin' rollin' up here.
Check out Metanet Hunter CD for our highest quality title, with Metanet Hunter SE being the next thing to try out. Maybe even try SE first, see if you like it, and then move to CD. I would steer clear of the original two games, but they're there for historic purposes.
