I'm sure that we have all had great times playing certain games. Even your favorite game may have lacked something, or had too much of something. So once you have played the game over and over again, what about any particular would you change to make your experience better?
Aside from all of the bugs, that have seemingly been ironed out with the various updates (I believe the they are up to update 1.4). I would have increased the amount of monsters that are actually in the world. I would have also made it possible to fashion the armor according to personal tastes by giving the player several choices of what the armor looked like. Kind of how they did with the initial character modeler. I would give the player the ability of fashioning dragon weapons which I believe that they completely dropped the ball on that one. I mean if you can have Glass, Daedric, and other types of weapons, why did they exclude Dragon weapons?
I kind of disliked the way that they make you build your character up as well, because you should be able to choose from a list of perks that you could buy during leveling up, but the way that they have it, you have to choose certain skills in order to get to the one that you really want, which wastes precious Perk points. I would have also included a hand to hand skill for those people who may have wanted to build a martial arts type character and add in all of the juicy bits that one might use as a martial artist, such as holds, kicks, limb breaks, take downs... etc.... All characters should be able to kick. That's about all for me.
