I am just noting:
WoW is an old fantasy MMORPG game that came out shortly before GW did.
Since then the mmorpg market has really exploded. Many new fantasy orpgs come to the market. Few make it. Amongst the most recent releases are: Vanguard (Fantasy), Lord of the Rings (Fantasy), Warhammer (Fantasy), Age of Conan (Fantasy) are probabaly the most famous example.
All these games have in common that a character in a 3-D environment gathers equipment, spells/skills, and experience to advance during real-time battles which often involves repeatedly slashing the same opposing character without seemingly doing any apparent damage apart for damage numbers.
This is of course a gross oversimplification, but my point is this. In most games, the game mechanics seem similar with no real innovations.
Some games go a different route by choosing a different genre (Sci-Fi or something else). Examples: Startrek and Eve. Others stay in the same genre but do a completely different game mechanics such as Dofus and Wakfu and seem to be really successful with it.
Most games seem to run more graphically advanced versions of the same game mechanics. Aion now has introduced the 3rd dimension to fantasy games.
My point is this: What will make GW2 so that it breaks out of the typical mold typical fantasy orpgs. And will GW2 be passed by the technological innovations time brings?
Of course my hope would be no. What are your thoughts?
