yeah, the invisible bounding boxes are annoying. Even in the smaller dungeons I could be a good foot away from the wall and the arrow will be stopped in midair, alert the enemy, and I shout at him until I can take out my sword and shield.
Combat doesn't seem that bad. It's adequate enough with some weird quirks. Like the visuals of an attack and how the game registers the contact feels completely separate. The enemy swings wide at the air, several feet from me, and I get hit; I hide behind a pillar/rock, the magic/flame hits me. It's better than Oblivion but it still has an off balance between action and rpg; this feels like morrowind flipped around to favor action. But it's still not good. VATS in Fallout 3/NV pretty much made combat a lot better in these games because it was RPG. Fallout 3 had whack action when shooting point black at a crab would miss, but New Vegas had a great balance.
Other things to whine about since I'm whining: the loot and money seem useless and I'm only about ~20 hours in. Again, it's not like the fallout games had great loot, it's just the damaging/repairing weapon system made loot more useful than "hoard, disenchant or sell." and that's back to the money, because after I bought my house, I have 20k+ and nothing to buy. And you can say "well just don't take all the loot and sell it, cool breeze;" but if I want to increase my speech skill for those persuasion moments, I gotta sell this stuff. This "do and get strong" system feels like busywork compared to dumping points into a specific talent.
I think that's about it. Game is really, really, really, really great. Uh, horses are really dumb and I wish I could tell it to "stay" instead of having it wander around and attack people; a way for magic users to summon horses would be best.
