what is warriors orochi...is it a significant announcement

It's another Musou game by KOEI.

It's only significant to people already a fan of their previous Musou games (like Dynasty Warriors).

In this case, it's a solid announcement - it's basically first two Orochi games packed in one. Now let's wait and see whether they have improved PS2 graphics...

Good score for Devil Survivor, seems like another great Atlus game I must play

@words of wisdom

so good in japan

but for us....meh x 100000000000

More properly titled:  Shin Megami Tensei:  Devil Survivor.

Here's a trailer:

Gameplay:

Thanks for the videos, I hadn't seen them. And for the music of the first video, it seems to be composed by Shoji Meguro, that's definitely a plus.

As for the game, I don't doubt that Atlus will add the SMT name to the western release so people associate it with the series, as they've been doing with all the recent titles, but in reality there are only three true SMT games. Not that I complain, though, everything that has the SMT name is guaranteed quality. And given that this game received the same Famitsu score as Persona 4, seems like this one won't disappoint

I don't think it's necessarily the SMT name but rather Atlus itself.  The more Atlus games I play, the more impressed I become with them as a whole.
