| Your observations, of course, are all accurate. However, I find them to be superficial, such that they do not make the game play feel like 1e in the slightest. I just don't see how movement in inches, or exactly which book a weapon comes from, is meaningful in terms of game feel.
The at-will/encounter/daily powers mechanics, the detailed reliance on positioning and movement, the balance of classes - all of these steer the game far, far away from having a 1e feel for me and my group.
YMMV, of course. |
