I like the roll-to-cast system in Dungeon Crawl Classics more. For one thing, it has spellburn, which allows you to burn luck -- or, in truly dire situations, permanently burn down another attribute score -- to push through a spell that would have failed. That way wizards aren't completely at the mercy of one die roll, but the price they pay for that can be incredibly high. (There are other things I like too, but that's for another thread).
I love Shadowdark, but the spellcasting system doesn't quite hit my sweet spot. But that's what house rules are for, right?
