That this game, even on master, can become really easy. Well mostly easy. I am still finding a ton of quests and dungeons I have yet to even enter. So who knows what bosses are lurking out there.
Some of my favorite fights are the ones where i get my butt handed to me for 20 minutes as I scramble to form a hint of a plan to take down the two handed cheaters. Sure I get really angry and start putting more perks into damage and upgrade my gear like crazy. But then a few hours later I realize I am just slaughtering everything until I get to the boss area. Then depending on a few things I get my butt kicked.
I guess maybe this is more of a personal issue then with the game. One that sometimes results in me completely restarting once I think things are getting too easy.
I got lots more to share... such as those two handed cheaters.
