Brock Allen wrote an interesting post on his blog comparing Ajax and the callback feature of ASP.NET. Most of the concerns he has about ASP.NET callbacks are addressed in my Fun with callbacks series and/or in the forthcoming Atlas project.
Wow, what a great game! I just finished Jade Empire in "evil mode". I'm very likely to do it again in "boy scout" mode. The immersion and richness of the universe are just amazing. The only thing I disliked is the tendancy Bioware has to explain to us that the evil path is somewhat as honorable as the virtuous one. I enjoy playing an evil character (I know the subtle difference between game and reality as almost every other gamer on the planet), but don't try to tell me that he's not evil. Some of the things they make you do in this mode are actually quite disturbing. I'm still waiting for the (good) game that will let you play a Dr. Evil-like character: evil, but in a funny way. Yes, Dungeon Keeper did that in a way, but that was a long time ago.
Looking back at all the feedback I got from my ongoing Fun with callbacks series, I understood a few things about what most people expect from an Ajax-like framework.
