I really like this game series you have here. Its got treachery, cool characters and nice combat and action. What I find really kills a lot of good things is the lack of music and even minor dialogue. The dialogue is a minor thing to consider but isn't essential by any means.
I think that to make the mood actually work in these games, there needs to be some kind of music to be played based on situation. When I play Fallout 1 or 2, the music tells me that Im in dangerous territory if I am in the Master's area or the Cathedral.
I think I agree with the developer in scraping dialogue, but music is a big problem. The music that he gets for intro screen is good. Cant he purchase 2 or 3 tracks per game for background based on area. If he adds music to the boss battle at endgame, it will be stunning!
I am not trying to sound like a jerk but if the developer adds the music to a certain game in the future, I can *guarantee* that he will have much higher profits. If he doesn't believe me then I already have proven it.
