class="wp-block-paragraph">So I just played <em>Skyrim</em> for (probably) the last time. And that&#8217;s a big deal. Let me explain.</p><p
class="wp-block-paragraph">I love playing big, sprawling, open-world video games. I&#8217;m not very good at it, so I always play on the easiest settings, but I love the immersive experience of exploration, puzzles, discovery, and (yeah) combat. Like many others, the game that defined the genre for me was <em>Skyrim</em>, which came out in 2011. I played it for several years, on various devices (PCs, handhelds, consoles), and every playthrough I found something new. (Sometimes it had always been there, sometimes it had been added in a new edition of the game or a mod from the Creation Club.) And from <em>Skyrim</em> I moved on to the various <em>Fallout</em> and <em>Assassin&#8217;s Creed</em> games, and then <em>Witcher 3</em>, <em>Horizon Zero Dawn</em>, and the <em>Ghost of Tsushima</em>. After each of them, I found myself coming back to <em>Skyrim</em> (and sometimes to <em>Fallout 4</em>), even though the graphics and gameplay were looking increasingly dated. Familiarity, I guess.</p><p
class="wp-block-paragraph">Last year Bethesda, the team that created <em>Skyrim</em>, released <em>Starfield</em>. It was widely panned. I bought it, played it through, yawned, and went on to other things. This year, the first add-on for <em>Starfield</em> appeared. It wasn&#8217;t all bad, but it was disappointingly repetitive: the main quest, culminating in a manic &#8220;<em>fight your way out of a collapsing ship/building before you die</em>&#8220;, had been done to death (pun intended). Enough. Oh, and the graphics weren&#8217;t a patch on <em>Horizon Forbidden West</em>. (Just compare the Va&#8217;ruun Citadel with a Horizon cauldron.)</p><p
class="wp-block-paragraph">Waiting for a couple of games to be released in the fall, I decided to do another <em>Skyrim</em> playthrough. Basic game, no mods, take my time, pay attention to the little details I often overlook. Without mods, the game really showed its age, but it was clearly a much better, more immersive, more carefully crafted world than <em>Starfield</em>. And even though I was stopping to smell the roses (and found some charming details I&#8217;d previously missed), I still zipped through the early part of the game, becoming arch-mage at the college, and signing up with Ulfric&#8217;s Stormcloak rebellion.</p><p
class="wp-block-paragraph">And then it all went wrong. With the Stormcloaks, I attacked Whiterun and defeated the Jarl. I returned to Ulfric, and waited for my next mission. He wouldn&#8217;t give me one. I wondered if I&#8217;d forgotten to finish something at Whiterun, so I opened my map. Whiterun had disappeared. I travelled to a nearby town, and &#8220;walked&#8221; from there to Whiterun. Even though there was nothing on the map, the town was still there, and the Jarl was still on his throne. There was no sign of the conflict, no loose end I could clean up. I travelled back to Ulfric. He still wouldn&#8217;t give me a mission, nor would he initiate the attack on Whiterun. I was stuck. And I didn&#8217;t want to go back to a save from a few days ago and go through it all again.</p><p
class="wp-block-paragraph">Even after 13 years, it&#8217;s not surprising that a game like <em>Skyrim</em> still has major bugs… but I don&#8217;t have to put up with them. That bug destroyed the spell. There are so many better games to play, and I will. Bethesda&#8217;s simply lost the plot, and for <em>Skyrim</em>, <em>Starfield</em>, and <em>Fallout</em> are history. (And so, I fancy, are the <em>Assassin&#8217;s Creed</em> games.) When I get back from Massachusetts, I&#8217;m going to replay the remastered <em>Horizon Zero Dawn</em>, and dive back into <em>Baldur&#8217;s Gate 3</em> &#8211; until <em>Avowed</em> appears, anyway.</p> ]]></content:encoded> <post-id

I wasn&#8217;t going to blog much about this, but I&#8217;ve found that although the web is full of text and video links for cataract surgery (in humans and other animals!), most are commercial or professional pieces. There seem to be relatively few first-person accounts of what it&#8217;s like to experience lens replacement. And since it&#8217;s a really cool technical fix, it&#8217;s worthy of the &#8220;Geek&#8221; tag.<br
/> I&#8217;m having my right eye operated on this Wednesday, September 21; the left eye will be done on October 18. In preparation for the surgery, I&#8217;ve just started eye drops three times a day: Vigamox (an antibiotic) and Nevanac (an anti-inflammatory). The pre-op tests took place on September 6, when they measured the interior and exterior geometry of my eyes using an ultrasound device; they&#8217;ll use these numbers to choose the right lenses for my replacements.<br
/> In peparation for the experience, I&#8217;ve been reading up on the subject and watching a number of videos. The best (lengthy) discussion of the subject is this lecture from UCSF:<br
/> <iframe
width="420" height="315" src="http://www.youtube.com/embed/zFqcvx5lEwI" frameborder="0" allowfullscreen></iframe><br
/> For a quick presentation of the actual procedure, this video is good, though rather low-res:<br
/> <iframe
width="420" height="315" src="http://www.youtube.com/embed/Sng6uZEt_TQ" frameborder="0" allowfullscreen></iframe><br
/> One of the things I&#8217;m particularly intrigued by is how much difference I will experience in my vision. Yes, I know that my eyesight has been getting increasingly poor &#8211; my right eye is around 20/80 &#8211; but the deterioration has been gradual enough that I probably didn&#8217;t notice the changes. I&#8217;m really curious about how my color perception will shift. In some areas I&#8217;ve noticed the changes &#8211; increased glare during night driving, for instance &#8211; and I&#8217;m looking forward to improvements there. I just read <a
href="http://www.allaboutvision.com/conditions/cataract-surgery-experience.htm" title="A Cataract Surgeon's Personal Experience" target="_blank" rel="noopener noreferrer">an interesting piece</a> by an ophthalmologist who himself had to have cataract surgery; as you might imagine, he was keen to document the experience carefully. (And it changed his professional outlook completely.)<br
/> <a
href="http://geoffarnold.com/wp-content/uploads/2011/09/cataractlens.jpg?6bfec1&amp;6bfec1"><img
fetchpriority="high" decoding="async" src="http://geoffarnold.com/wp-content/uploads/2011/09/cataractlens-300x195.jpg?6bfec1&amp;6bfec1" alt="" title="Cataract replacement lens" width="300" height="195" class="alignright size-medium wp-image-4195" /></a><br
/> Anyway, more and more of you will be going through this process over the next few years, so I&#8217;ll try to blog regularly about what it&#8217;s like.</p> ]]></content:encoded> <post-id
