How exactly is Shadowrun, a 2D scion of the 16bit era, a bigger project than a 3D motion capture title with high production values?
Well, Shadowrun was always more known as a pen and paper RPG series, than it's 16bit games. But that is really hard to say on Shadowrun's part. It really all comes down to things like voice talent, soundtrack composer, and game artists. It really depends on how they distribute the budget for the game.
But Shadowrun is already based on a recognizable name, has a pretty well respected game designer helming it. He created the Battletech board game series (the Mech Warrior series was a spinoff of this) As well as the Shadowrun P&P series and worked at Microsoft game studios on games like Crimson Skies.
Also, Shadowrun is being Targeted for Windows and Mac (and Possibly Linux).
Now, Republique is a game that is being developed by a group of fresh young developers who were underlings at Kojipro. Their project is very ambitious, but they are aiming it at a platform that is making this a very hard sell. If this game was a aimed at PC/ Mac, I believe they could've gotten as much funding as the Banner Saga did. But it seems like there are quite a few factors working against them.
