Pros: Great graphics and visuals Great music and sounds Story bits are well written and acted out Character creation is pretty solid, lots of options Cons: Mechanics are 5.1 ish, its more like a homebrew than a true DnD so there is a learning curve even if you are familiar with the srd. Dice rolls are artificially lowered, you will get a lot of nat 1s when rolling attacks and damage, making combat sometimes needlessly hard if down right impossible. Meaning in most cases you have to use some pre-determined strategy in order to win fights. Level cap at 4 is reached about halfway through the current content. So for half the game you're staring at a full xp bar while encounters keep getting more and more advanced.
So yeah it has a fair amount of bugs and glitches, but it is no more than one would expect from such a huge project. To be fair Elder Scrolls and Fallout games were much worse at launch than this one. The world looks amazing and it is incredibly dense. Tons and tons of stuff to do as well. I'm on a second more thorough playthrough and I am 40 hours into it and barely 1/5 of the way throught the story. The best way to keep bugs and stuff from affecting your game too much is to quick save and load every couple of hours. I've been playing these type of open world games since Daggerfall and Fallout 1 were new, and this is probably the best game I have ever played in my life. Just keep in mind that this is the worst state that the game will ever be in and it is still an incredible game. It only gets better from here. So if you are wary then wait 3-6 months then jump right on in and enjoy this incredible experience.
