Guild Wars: Nightfall
So, my reaction to the game: in a nutshell, great. The new Hero system in particular really adds a lot to the PvE but there are a lot of little details that add up. Artwork is gorgeous as usual - running around the sandy beaches, I caught a flash of a shark's tail in the deep water last night. The new "master difficulty" quests are a nice touch - although with my limited progress so far I haven't found anything too tough. The community reaction has been very positive and it's hard to find "hate" posts as there was after the release of Factions.
In PvP, the 2 new classes - Dervish and Paragon - are seeing a lot of play but so far noone has figured out anything totally broken. There's a few new skills that seem very strong but it's unclear if they're actually overpowered. Keep your eye on Rampage as One, Searing Flames and Energizing Finale. A polite golf clap goes to Izzy (Isaiah Cartwright, ArenaNet's skill designer) for managing to create distinctive and useful new professions. The metagame hasn't stabilized yet and so all kinds of crazy Dervish and Paragon builds are showing up. Fire elementalists with Searing Flames are all over the place right now which makes a pleasant change.
I'm playing a Dervish in PvE right now and it's a lot of fun. Paragon's up next.
The new PvP template feature released just before Nightfall - saving and loading skill and equipment settings - is really good too. There's only 2 things that need improving with the feature:
1) When you save an equipment template, it only saves the current weapon instead of all your weapon slots. This is dumb and wastes a bunch of time when you're re-loading a character.
2) Since you can't copy out of the GW chatbox, there's no easy in-game way to send a template to someone. This isn't too bad because you can just post it in the TeamSpeak channel or whatever, it's more of a quibble.
