knowing Devil's Third is already set only on Amazon JP. and i believe limited for europe as well. NoA doesn't know if they are going to publish it or not and when. So it would still be Godzilla just for the name and I believe fans would buy it once it is really on sale.

edit: NoA would publish this in Americas. and would push to Q4 2015.  PC would have a version of multiplayer with microtransactions.

Why the comperison?

I guess godzilla. how much had it sold in japan?

Gojira

Godzilla

People at GameStop or whatever will be like: "I am not buying the game, I haven't even played the first two..."

Two games with apparent rocky reception.

Two games with apparent low sales expectations.

Two games releasing relatively close to each other.

Two exclusive games from different companies facing each other bandwagon, but with hopes of no need for heated fights as no fanbase will go up in arms for either games.

Pick one.

Godzilla because multiplat and bigger userbase

Not sure. It could go either way.
On one hand, Godzilla is on playstation and it has its title.
On the other, Devil's Third is exclusive and it's multiplayer mode will be free on the PC, so it could attract alot of people to buy it.

Godzilla

Way too easy, Devil's Third. The game is in headlines more often, releasing during a period where potential buyers are more likely to spend money, and has a guarenteed following because of Itagaki. And really, people are overhyping the shittiness of this game. It still looks terrible, but not as bad as previewers are making it out to be...
