I know this is going to turn a lot of people off from the idea simply because we are all veterans that know how the game is played now. So reminisce to the time when you were a new player or how your friend that has never played would like to be introduced to the game.
While I love how Square dumps you right into the game and involves you by tying you into the story. I think the reading the more advanced nuances of the game in in-game text gets to be a bit much. What I mean by that is too long didn't read syndrome.
Game functions like, combat, combos, player attributes, crafting (because it's completely unique compared to other MMO's) etc. Need to have either an in-game tutorial or an offline website dedicated as a tutorial for the game. One that has videos that show examples of how the game is played.
I would like to see included in the popup help little camera icons to show related videos for the intended material the popup help was for.
I'm not talking about the simple stuff like, WASD is for movement. More like explaining how HP, MP, and TP is used for, what the positional icons and numbers on your abilities stand for. Strategic value for using certain abilities in combat, possibly even showing uses for when solo and when in groups.
All these videos can be laid out in a Table of Contents that can be browsed through by section. So Combat would have combos, abilities etc. and Player would have attributes, gear sets. etc. So while a total comprehensive in game tutorial can gloss over the simple stuff. This pop up videos could be dug into by player choice to find out the more advanced features of the game.
All I know, is I hated crafting for the longest time before I understood how to read the colored lights and my professions abilities. How to work Hamlet defense would be a nice tutorial too! You know something to send newbies to go watch before joining your party so they don't cause a wipe! lol
A nice example of website tutorial with videos like what I'm talking about is Mechwarrior online. http://mwomercs.com/game/training-grounds
Now I know it's not an MMO, but this game is very technical in nature and I like how it walks you through the classes and controls and how you will use them in game. I think something similar for FFXIV would be helpful to have on hand. Especially when we are throwing in Housing, getting your chocobo. etc.
Maybe this is to much like a strategy guide, but we need people to play the game. Not have people get frustrated and leave, because they are used to playing WoW. These players were adventurous enough to try a new MMO, yet since FFXIV was so unique they left frustrated not understanding how to play.
After all we don't want a WoW clone, we want FFXIV:ARR to remain unique without testing peoples patience on how the game works.
