Well, I find your post slightly overzealous. In all honesty shure there may be problems with the grapics and such but in a glance it actually looks extremely good, especially if you consider the fact that compared to D2 it is by far past the "Next Gen" for visual quality. You also need to understand that not everyone can afford to just go out and buy a new computer whenever they feel like. Alot of people will be lucky if they can even afford the game when it comes out. Not to mention the vast thousands of people who are losing their jobs with each passing day. All in all it is not only a question of Blizzard trying to morally fair and allow as many different computers be capable of playing the game as possible but it also alows them to have a greater return on the game. IE the more computers that can support it the more copies they are likely to sell. So why do you keep trying to bring up the same point over and over especially when your primary answer has already been given, Anti-ailsing. I'm pretty shure they very much plan on adding it into the final game but I doubt its a major priority for the time being as the majority of the game as far as we know is still under development.
So you can sit there and say I'm probably some stupid kid complaining because I don't have a good computer so on and so forth. The fact remains that I'm right though, not to mention from what I gathered yours is like 3 yrs old? Yea, mines like months! :)
Anyway, just some thoughts. Oh, and I did read all your posts, not to mention baishoks, and the 2nd guys post. Honestly I think most of the others just came here and spammed it because Baishok posted on it. I know I looked because of that. No sense in weeding through alot of the crap posted by people on here so I figure if he posted maybe its worth reading.
