It's been said, but I'm gonna say my piece too.
We had high expectations... For those of us who enjoyed FFXI (which is probably the same target audience for FFXIV), FFXIV was a HUGE let down. I loved FFXI and played it for a few years. I lvld many of the jobs, had 75WHM, ran Sky, Dynamis, so forth. I was incredibly excited when FFXIV came to beta and I tried it out. Yes it's a beta which means it's NOT a finished product. But it was so far from being a good product that I couldn't stand to play more than 5 hours of it.
Yes even FFXI played better with a controller, however I never did and I felt it played just fine on my laptop (had default keyboard controls for 'compact' keyboards, i.e. laptops). FFXIV was nigh un-playable on keyboard. FFXI had a better list of configuration options. FFXI had better maps (not environments, the actual 'map of the town' maps).
Now you might say "Oh you're just an FFXI fangirl", well maybe. You might also say "but FFXI was out for years and they had time to get it good, so of course FFXI is better now than FFXIV", sure but here's the biggest sticking point. Any company that has EVER made more than 1 MMO, the 2nd will often be better than the first, more polished than the first, more enjoyable than the first for a simple reason: THEY HAD TIME TO LEARN FROM THE FIRST!
The things I felt FFXIV blatantly lacked were things that were in FFXI that they could have learned from.
And as for us having high expectations? I assume he is referring to his target audience, those of us who thoroughly enjoyed FFXI... well of course we had high expectations, we enjoyed it! SE may be failing lately (and I am quickly losing respect for them), but they used to make good games, so of course there is going to be high expectations. Think BioWare could make that excuse if Star Wars: The Old Republic comes out and people don't like it? NO! BioWare makes good quality high-rated games, and they have already set the bar for all games they release making it abundantly clear that all BioWare fans WILL have high expectations from their up-coming MMO.
And only 630,000 copies shipped to retailers across the globe?... I'm sorry, those numbers are a bit sad. Now I understand MMO's don't get the same "pre-order and release day sales" that single/multi-player console AAA titles get... but that's still a bit sad. And given that Japan themselves had the lowest amount of copies... that should be a red flag first off. It's a noble goal to make a game that is loved across the globe, but worry about your people first, your own livelihood depends on their tax-money (or however their system works).
And if anyone who pays attention to other MMO's has noticed, the average 'lifespan' of an MMO (looking at 'high-pop' times, not the time servers stay online for good) is very short. If you don't catch people soon, or bring them back soon, you're doomed to fail. And sad to say... this is doomed to fail. SE, please stick to publishing games at this point... you're better at that than making games now.
