2.Warhammer: Never played the game maybe someone else can fill in this blank.
Warhammer was a real shame really. It had great potential but the developers focused too much on certain things and neglected others to the extent of creating an incomplete game really. There are some great innovations that every MMO should implement:
1. Tome of Knowledge. It basically records everything you do and gives you rewards for accomplishing certain tasks. Sometimes the reward is nothing more than a line in your tome saying you did it others it's a title and sometimes you get a trinket that has no use except it adds a bit of style to your character. WoW also has something similar with it's achievements that many think was copied (I honestly think Blizz did a slightly better job with it).
2. Public Quests. These are quests that surround a certain area. Everyone who enters the area automatically get the quest and can participate whether or not you are in a party. The rewards are based on your participation as well as a random roll. The roll is if I remember correctly from 1-1000 and those who contribute more get awarded points in addition to the roll. Also, if you didn't get any reward the last time you participated you get extra points...this way you can't do it more than a few times without getting something. You also don't automatically get assigned a reward but are given a list of items to choose from...that way you don't get something you don't need. It is also timed so you know exactly when the PQ will start. It's a rather ingenious system and I honestly think this is the perfect way to do HNMs. It would solve a number of issues: A) with the timer you would know exactly when the HNM would spawn so you wouldn't need to wait forever or find out when the spawn window is, B) there's no way to loose the reward because someone claimed it before you did, C) there's no way you could get cheated out of an item since the rewarding is automatic, not divided out by your group leader. The problem is if we kept jobs like RDM it could be hard to determine it's contribution to the group if all it did was enfeebles or buffs...I'm sure there's a way to do it though.
3. There are also a number of PvP related innovations that are pretty good but probably have no place in FFXIV so I wont go into them.
EDIT: Oh, I forgot the UI. It was completely customizable...you could change the location, size and visibility of everything. Edited, Jun 6th 2009 1:58pm by Yogtheterrible
