I bought it after the demo, and while it definitely hit those highs again, the demo didn't show just how low some of those lows would be. I made it about 60% though the game before abandoning it out boredom. While a demo is great, it is important to remember you're likely getting a vertical slice of some of the best bits.
The demo really made me want to get it and actually caused me to preorder. I wasn’t even that excited about it until the demo. Once I turned it on and heard the music that instantly transported me to final fantasy, I was sold. Wound up shelving Diablo until I finish the story for final fantasy. It’s long and I’ve loved every moment. The side quests, while being typically fetch quests, have great stories in them that really build on the world.
Sorry, this was supposed to be about preordering and turned into me gushing about final fantasy.
