Witcher 1 and 2 are RPGs that do this the right way. No morality meter, just hard choices without full knowledge (so you can't be sure which choice is good, often neither) and with delayed consequences (so players don't just reload).
And in TW2 they made a whole chapter (+-20% of the game content) different depending on your choice, with different map, different NPCs you meet, quests, and you get to know different aspects of the story (if you play just one version you won't get the whole image).
