Following reasons I can see to pass on the first edition:- Big box is not for everyone. Some just don't have the space for them.
- The expansion and possible future expansions won't have 3D mountains. So you'll have some mountain terrains with 3D mountains and some without.
- Also, in case of future expansions, new races will probably not get thick cardboard as race sheets. So there will be no uniformity. (Though there is no gameplay interferences)
- Maybe the biggest issue: The revised edition has changed rules already printed on cards and cardboard. Like the hero movement on order cards or the changed Latari-elves ability.
Thats all just for information. I would always go for the First Edition. Component quality is just better.
