Oh man, I love what you're doing with this!!
I haven't played Oblivion (or any of the Elder Scrolls games, it's on the long long list of things to play) but having played Fallout and knowing that the open-world mechanics are (relatively) similar between the two because Bethesda it was easy to follow along. You really captured the feeling of finishing the opening sequence and being let out into the wide, open world, free to do whatever you'd like -- whether that's following the plot or roaming the world until you stumble upon a quest that interests you, or just wandering into a dungeon.
(Honestly, one of the reasons I haven't played the Elder Scrolls games yet is because I know I'm going to pour hundreds of hours into them, because that's how it was with Fallout. Thanks, Bethesda...)
I really love that you've focused on nature and plant life for the first essay! It's a really unique page but very interesting; I love all the real-world comparisons. It does end a bit abruptly; perhaps consider adding a conclusion that ties your thoughts together on the subjects you've discussed on the page? Or perhaps discuss how these plants are used in the game in more detail.
Definitely looking forward to more!
Also, I love the layout -- as always, your typography is lovely.
