I wish half the games that came out were originals. That shouldn't be a complaint about Sega alone. Fuck, even Treasure is rumored to finally be doing a sequel. As for the titles i listed, there were substantial gaps between them. That's not the case with every Sega title, but it is true of the 3 I listed. Outrun came out in the late 80's, this sequel (wasn't there another Outrun 2?) just was released, Panzer Dragoon Orta was released 4 or 5 years after Saga, and Vf4 and VfEvo (I know I listed Evo only) was released a couple years after Vf3.
THE ONE, THE ONLY- RCM
