Did they even play the game? What meaningful choices?
Nothing you do in Skyrim affects anything or anyone, with a very few exceptions.
This is the worst Beth game to date when it comes to choices and consequences.
The only "meaningful" choices I've had are the ones I've been RPing myself.
...How many Beth games ever had meaningful choice? Oblivion certainly has less than Skyrim, as does Arena. Daggerfall arguably had a bit more although with all the random quests there wasn't much to it (the devs even said they felt it didn't have enough). Morrowind has some choice though it's rarely meaningful, the rewards tend to be instant, and the game isn't quite as aware of world events as you'd think. Fallout 3 is the only Bethesda made game with any real meaningful choice, and it's considered inferior there to F:NV (not Bethesda)
Bethesda games have rarely had meaningful choice, though it would be a welcome addition
EDIT: Actually I just checked, Daggefall has none, barring the multiple endings. There is not a single thing you do in the MQ that was a choice until you get the totem, nothing that affected things in the long run (you could give a few quest items to different people, but the reward was instant, and only affected the broken reputation system). Other "choices" such as which Knightly Order you joined were very unimportant, as they all gave exactly the same quests.
