ES4: Shivering Isles - Review @ BRnR
A lengthy review of Shivering Isles with several in-character bits is up at the wonderfully named Barry's Rigs 'n' Reviews. The score is 8.5/10 and here's a snip:
Bethesda has taken the combat routines for the game’s new enemies up a notch from Oblivion and Knights of the Nine, making them a little tougher and more aggressive in their pursuits and attacks—a welcome change. Some are able to cloak themselves and can’t be seen by spells, potions, jewelry and armor that detect life. Some absorb spells and regenerate health faster than you can deal out the punishment. Some you should avoid fighting in water or the rain (or kill as quickly as possible), as it makes them stronger. Some grow larger, stronger and immune to any single elemental spell (fire, frost or shock), requiring that you hit them with multiple elemental spells with opposite effects, or use normal weapons to take them out. The latter option is perhaps the best approach, since these same creatures are quite proficient with their ranged Silence attacks, preventing you from casting spells at all (not all of them are hostile however, and some can actually help you).
