I like finding bodies with little pieces of evidence (like journals). It's fun discovering what happened.
I do as well. Theres a couple of places ive seen so far (one in particular right outside whiterun, around the outer wall to the right when exiting the main gate... There is a stream and it runs into a pond or small lake) there is a skeleton arm sticking out of the lake holding a sword... Its awesome. I made a sick picture for my save screen. Lol. Theres another in a lake by that eldergleam area by mistwatch... A skeleton with a sword stabbed in its back. I left the weapons alone. You know, just incase it screws with somethin.
I also love the bugs. It adds so much depth. And finding journals. I find it more rewarding to read journals rather that most books. And i love how i can be caught off guard by wandering wildlife when im too busy harvesting clams or snowberries. And everytime i see a poor dead rabbit, i search for that sabre cat or bear so i can avenge fluffy.
The dungeons and caves are incredible. No more basic-ness like in oblivion. I love walking in to a new cave and theres glowing mushrooms lighting the area. ...sometimes theyre a pain in my a$$... And i cant just pick them all for some reason... Im trying to hide stupid shroom!
