in my opinion the AD&D magic system is oudated in regard of all the rpg of these years
ok obsidian would like to retun on an old school, but if that means go back to the AD&D first version, i'ts useless
i think that the way that AD&D use magic is not fit for a video game, it's breaking the rythm of the game because of the multiple rest for the mages
your mage got 8 slot of magic (so a 8 or 10 level mage), an average combat use 2 or 3.... that means you MUST rest if you dont want to die after just 2 fights, especially if your party is full of mage or priest
so i prefer an ability system, but a with a mandatory on wich magic you wich to use, like enchantment or fire, with the possibility to have a new one all x level
our mage got a line of spell and some point to spent in at each level
but i would like if, like in arcanum (cf the post), we have the possibilty to learn new spells buy from a merchant
(sorry for my poor english ^^)
