GW is a beautiful and fun game. Even the crystal desert, after all these years, looks better than much more recent additions to WoW, imo.

If I could have changed any two aspects of GW, it would have been:

(1) Decrease the maximum party size to 4 or 5 (8 is just too many)
(2) Allow players to switch (in outposts) between "open" (persistent, no heroes or henches) or "closed" (instanced, heroes/henches) modes, with the regions then scaled appropriately depending on the mode chosen

Those two changes would have, imo, made GW just about perfect.
