It is, oversimplified, your standard theme park MMO in terms of functionality and interface. It has the Final Fantasy feel to it, and content-wise, it is clear they're intending to take elements of various newer MMOs and implementing them accordingly (dynamic events for example). I don't expect a reinvention of the house, but I do expect a good house. They have the foundation to make it happen with their new engine. If the alpha had been a travesty, I'd have moved on yet again. I was surprised to see it run as well as it did in alpha, which is phenomenally better than how FFXIV 1.0 ever ran even after dozens of patches.
They've given me nothing but good vibes so far. They've been forthcoming every step of the way. I'm definitely onboard.
