Having recently played rather a lot of GW2, I've become increasingly annoyed with the presence of zombies and other assorted undead and/or risen stuff everywhere. It's not that I have anything against zombies per se - it's the quantity that's getting to me. They are everywhere. Games: zombies. Fantasy books: zombies. Films: zombies. And now with Halloween approaching - more zombies! Seriously? That's not even creative. The last quarter of the storyline, not to mention almost all of the endgame content in GW2 is spent fighting zombies (ok, the lore has something to do with that, too), but if it has to be undead, at least make it look like something interesting and not like your everyday Whatever-of-the-dead antagonist. Especially in games, there isn't much that you can't do in terms of design, and I find zombies just such an easy, cheap way out... and they stink.
Apart from that, I'm actually really enjoying GW2, and my newfound freedom after handing in and defending my thesis
