Since FFXIV is supposed to be a current gen game (and not a last gen game) what are some of the things you're seeing from other games and how they can be applied to FFXIV where necessary.
1. Extensive Voice Over - GW2 and SWTOR
People don't like reading walls of text anymore. No discipline I guess. So in order to get people more immersed in the game, voice overs seem to be used more and more. You don't just read the text, you hear it too... and in GW2's case you don't even read it.
2. Advanced char creation - EVE, super hero games, AoC
People really like to customize their avatar as much as possible. Selecting from one of a few options just doesn't cut it anymore. They want to tweak the nose, eyes, lips, chin, overall body type, and boob size. Likewise people want lots of ways to customize their armor and looks. In other words they want to stand out and look different from everyone else. They want to make their ideal char.
3. Dynamic Content - Rift, EVE, GW2
Eve just added incursions, areas where one NPC group takes over and people have to band together to get rid of them. Rift's rifts have the same effect I hear. In GW2 there are dynamic events and they operate in a chain of sorts (you complete one it goes away or back a step, if you fail one, it goes to the next step), the things you can do in an area change as well (ie a village gets burnt down, no more vendors until you drive away the raiders).
4. Dynamic Combat - GW2
Warriors have attack chain skills, as you keep using that skill slot it changes into the next skill in that line. Elementalists can change which element they are using on the fly. Everyone can switch weapons in combat (between two sets) and this changes the first 5 skills on your bar. If you get downed you get 5 skills just for that. Skills interact with each other (swing your sword through an allied fire zone and your sword catches fire). There's dynamic grouping so you don't have to party formally to team up against a mob and everyone gets a reward.
5. Lots of lore/storylines - GW2 and SWTOR
Only a little bit of lore and story here and there isn't good enough anymore. People want to be involved and invested in the world. Who are the people and NPCs? What do they want? Why do they want these things? What are the events of the world? How and why are they impacting things? What are the fundamental ideas that are in conflict and why?
These things are all that I expect the current gen to have. The first isn't so necessary and is pretty expensive. I'm sure there are more things, I just can't think of them right now.
