Fortunately for them, they already got your money. That's the Bethesda MO... over-promise, under-deliver and fans will justify the rest. How many endings was FO3 suppose to have? I fully understand liking something that has flaws, but they shouldn't be excused because of it.

But it doesn’t have the same RPG elements as I was hoping

I feel like hope wasn't warranted there with the obvious streamlining trend since Skyrim*. I could maybe see being cautiously optimistic, as in waiting for reviews.

Not that it comes as a shock, I'm sure I'll hear others say the same with the next elder installment.

*=They at least made an attempt with FO3, skill checks+perks (plus the XP system is less grind-y than Oblivion even if it is simplified and less "immersive"). Also improved upon by FONV. (I didn't have a good start with Morrowind, in fairness it probably was my fault for some of it but I don't think skill grind and dice-roll misses are a good combo plus needing meta-knowledge even if that's what makes replaying fun... because slog.)
