Journal- being able to edit entries would be nice, i ended up doing a lot of cutting and pasting to the notepad and creating and deleting entries, and a simple edit feature woule have been very helpful.
also, be able to add info from scrolls, signs, books, etc to the journal, as i found a lot of info on bookshelves that i liked and wanted to keep, but i had to handwrite it all down.
also, I dont know if this is possible or not, but alter weapons and armor so that there is no one 'best' weapon, but that different ones are suited for different purposes, like swords would be good against soft/unarmored things(people, critters, etc) and maces would be good for armored/hard things(crabs, ruffians with armor, etc)
I dontknow if that can be done or not, i dont know the least bit about programming, but i think it would be nice if the different weapons and armor had thier strongpoints and weakpoints.
also, could it be possible to find slingstones? I would imagine that pretty much any fist-sized rock would do, so you should be able to find them lying around the ground and such.
also, make level advancment a little easier, i kinda got stuck cause i spent all my points on battle/magic skills, and i didnt learn how to cook(i figured i wouldnt need it since i could kill critters and ask the land-king-hall cook for food)
oh, and maybe some spell that can sort of 'proof' you against spells like fear and confusion, or a potion that gives you a resistance/immunity that you would use before getting in a fight with a demon
thats all i can think of for now, maybe ill add more later
oh, and make the world bigger
