I have never played WoW but i have played several other games like it online. I played 4e for awhile to see how it would play.
To me it is more the style 4e pushes forward the most. Some other posters covered some aspects. yes previous editions to a point had some of the same stuff but 4e has pushed them more forward.
And for me the game play with the power system reminded me of online games. No it wasn't the same or even mostly the same, but it did have a slightly greater feel for that than previous editions did.
But what you are asking is for peoples opinions and thats all they are. What makes something feel one way or another or why someone likes something or other. Is often a matter of perception.
This thread isn't going to get to the bottom of anything I doubt, nor is it likely to change anyones mind and it just might start up a flame war.
The bottom line is 4e is what it is and either you like it or you don't. It reminds you of what ever it reminds you of or not, due to ones own personal experiences.
Ok done rambling hopefully this makes since but it might not, it is well after 4am locally. Still dealing with insomnia as I have been all week and I am getting a bit slap happy from lack of sleep.
True enough. It all comes down to opinions, and I've learned that most people are not willing to change theirs. Like it or don't.
By the way, I hope you get over your insomnia; having dealt with it myself on a number of occasions, I understand how much it sucks.
