When I mean more side quests, I don't mean more guildleves.
My biggest gripe is there is hardly any content. You have the main story line every 10 class levels, but everything else is a guildleve. There are no other stories to pull you in. You have a city full of npcs, but besides the vendor npcs and guildleve related npcs, there really is nothing that the other npcs do. There's no child that lost their pet, there's no old man that needs some plants to create medicine, etc. There is no satisfaction that you're helping the town or saving the world except for the storyline quest. I realized that a single quest to run the whole show works if you're playing a single player game where you're leveling as you're progressing through the story, but when you have to level 10 levels to get to the next part of the story, you start to lose interest unless there is content in between.
Now I'm going to compare FFXIV to another Square-Enix game, Dragon Quest 9. Yes, a Nintendo DS game. Why was it that I can sit down and spend hours grinding on mobs in Dragon Quest, but I didn't really want to do it in FFXIV? The reason was because there was a reason why I was fighting those monsters. I had quests to do, I had either collect some magic item that this certain enemy drops or I had to perform a maneuver X amount of times, in order to help the npcs that gave me the quest. Now while I'm doing these quests, I'm leveling, and I'm getting stronger to do more of the story. I am really not noticing the grind that much. In the end, I'm helping out the poor npcs that needs my garbage loot, or I did find that lost puppy that was eaten by one of those carnivorous plants. I feel accomplished, I had a reason to fight.
Now take FFXIV. You start the story line quest. Okay run from here to there to there, talk to this npc and that npc, and quest completed. Alright that was a fun introduction. Now what do I do? Who needs help? Well there are the guildleves. Alright take a few of them, and start them. Kill X in Y minutes, find 3 prospective mining spots, dig up some high quality ore. Alright I did them, now what? Oh here's my reward, awesome. So why did I have to kill these monsters, why did I have to get some high quality ore? Look at the guildleves this way, they're not quests, they're want-ads. There's nobody saying "thank you", no smiling child, it's finish your job and get your pay. There isn't even a surprise in the reward, the guildleve tell you how much it pays.
The game so far is like a job. You log in, then you either craft, sell or buy stuff, or go to the guildleve for more work orders. There is no satisfaction that you're saving anything or helping some lone character. I do get satisfaction when I'm supplying a crafter with materials they need (the bazaars where the player is buying X materials), but the rest of the time it's "awww... I got the 'kill dodo' job again. Well, another day another gil." As I watch the intro movie again, I see the characters excitedly trying to figure out which guildleve to do, I watch the battle against the malboro. Now if I was there and asked the characters why are they so excited or why are they battling that malboro, what answer will I get? I bet they wouldn't know, or that they'll say they get 10k gil from killing it.
