The graphics are sub-par, but not because of the resolution. There are some games in that list that use the ''latest'' technology, but look unappealing to me never the less.
However, Dave Gilbert is an excellent writer, he has proved himself many times before. I'm looking forward to his next game, which features artwork by more capable artists. Great graphics combined with his excellent writing skills will prove to be a killer, I'm sure.
As for the voice acting, yeah, quite good. I read he's got some connections in the field.
