first of all let me say you've done some very interesting work here and it's cool to see!

a couple of bits of information and critique for you

baldur's gate is based on dungeons and dragons rules...for better AND worse, and a lot of your improvements can be found in newer computer games based on D&D, such as neverwinter nights 2, it has already incorporated a lot of the elements you have suggested to improve the game.

that being said, baldur's gate was based on an older version of the game, the new rules or "ver. 3.5" allows for a lot more customization. you can, as you said before, mix alignments and races and classes however you want, with fewer restrictions...eg. a paladin still must be lawful good, etc.


combat has improved, you can set traps, have spellcasting and movement planned out better, etc.

unfortunately the vampire is already a monster template that adds a lot of character levels and turns the character evil, so it has not yet been incorporated into a computer game for that reason...this is not to say that it can't be done, of course!

if you want info on neverwinter nights, go to www.nwn2.com
and the D&D rules are here http://www.wizards.com/default.asp?x=dnd/whatisdnd

i suggest clicking the 'play the demo' version for a taste of what the tabletop combat is like at low levels

hope this has helped
