Thanks to Laurie W, who writes "Sudhain.com has a great comparison of D3 vs. HL2 (funny, too)." From the article: "Since Half Life 2 was released this week, I thought it'd make a good time to take the two games head to head and see which came out on top. I've spent a few hours in the beginning of each, playing through the first few levels. Although I haven't completed either, I've spent enough time in each (I think) to develop a feel for what the later sections of each game will be like. Given that each has been fairly consistent thus far, it'd take a major shift for my opinion of either to change significantly."
