this is an old thread, but i'm new so i haven't been able to voice my opinion on dirge of cerberus, so!
i personally didn't like it much. HOWEVER i have yet to finish it. i had heard a looot of negative things about it, so my friend and i decided to marathon a bad game. and since i had dirge and hadn't played it...
the gameplay was pretty awkward but i actually picked up on it pretty quickly so it wasn't so bad. i didn't like it much but i mostly didn't care for the story.
it's cool that square tried something different, though. respect.
