This game is like a drug. Quitting just ain't happening.
Glitches aside (PS3 player here)...
I love the fact I can get totally distracted doing absolutely nothing sometimes. I'll sit down to play with a mission in mind, after an hour I'll not have left town....
I enjoy wandering the world, doing the whole self guided tour guide thing is a lot of fun. There's a lot of nooks and corners to be discovered which have goodies.
I do like my 2 characters thankfully. I didn't at first, but now they've grown on me. Both have given me a lot of good visual D&D moments we usually joke about when table top gaming. Only dislike here was in creation. Wish there was some adjustments you could make to age so the guys all don't look like they're 45+ years of age (the women look okay. They look mature, but not 'old'). Also wish the clothing you wear was cleaner, or had more options of cleaner gear. Some of those robes are nasty stained.
Love sneaking into an encounter with people who hear me sneaking, start searching, and push me aside full force, without seeing me of course.

NPC: Runs over and shoves me out of the way in search mode. 'I thought I heard something!'
PC in sneak mode: 'Uh, chirp, chirp, nothing but us crickets.'
NPC: 'Hmph, must have been my imagination.'
PC: 'Chirp.....chirp...chirp'
NPC: Walks off.
PC: 'That...actually...worked? What a moron!' BACKSTAB.
