i bet i'm in the great minority here (what a shock! <img src="/ubbthreads/images/graemlins/stupid.gif" alt="" />), but while a laser cannon would not satisfy, i hope like heck DD2 has tougher monsters and considerably harder difficulty settings.
playing through DD and BD on hardcore left virtually no challenge at all from the monsters - even bosses.
without the 'fear' of dieing, the story is all that's left to carry the game - DD succeeded amazingly. but most games can't pull this off, story alone.
so my greatest hope is that they deal with the only real 'complaint' i had (that i couldn't live with) and make the game more difficult - at least the option for the players to make it so.
but no laser cannons. <img src="/ubbthreads/images/graemlins/biggrin.gif" alt="" />
