A few days ago my brother, in one of his typically off-the-cuff ways, said to me - "it's good, but there isn't as much to do as Guild Wars 1 is there?". I grunted, not necessarily in agreement, but not totally in disagreement either.
It's not a criticism of the game, as such, just an observation of where we stand right now. Guild Wars was a reasonably big game when prophecies came out - with the PvE campaign and numerous PvP formats to get to grips with (TA, HA, RA and GvG). Each year following the release the game was further expanded - Sorrow's Furnace, Factions, Nightfall, Eye of the North and the Guild Wars Beyond features added substantive content to an already jam-packed game. Hard mode effectively doubled the amount of PvE content available in one fell swoop and PvP has expanded to additional game modes such as AB and HB.
There isn't as much to do right now in Guild Wars 2 as there was at the end of Guild Wars 1. But Guild Wars 1 had the benefit of almost three quarters of a decade of updates, expansion and fine-tuning. If the new game starts off with even half of the current content that the original game has, then, after a year or two GW2 will end up being a game world of absolutely mind-boggling proportions.
ps. that last sentence was a bitch to write.
