Choices in that game have a notable enough impact to keep me satisfied. But games where you can be either good or evil tend to always end up with you saving the world or whatever regardless. I'd be interested to see how many games out there are played out in such a way that you can actually have two entirely different plots, one good and one bad, or perhaps even more branches.
Part of the problem with choices and impact is that either you don't have enough power so the powers that be continue to move towards the inevitable (New Vegas though I would argue the endings and outcomes do change big time depending on which one of the 4 sides you choose). Or you are so big and bad assly powerful that your choices would have such an impact that it is practically impossible to build a story around it.

One of the few games I have played where choice matters and has a huge impact is Phantasy Star 3. The choice you make in the game is who to marry and then you play the next generation and choose a wife again and play the final generation and they are all different quests.
