I own the game and enjoyed parts of it, without going into details, I thought the mechanics were fairly good, stuff like flying around, the feel of the different Javelins, the shooting and abilities were good. What wasn't good was the gameplay loops, loot and overall anything you did at the end game.
I had forgotten about the game, forgotten they were doing a 2.0, and the announcement doesn't really excite me. The most it manage to get from me was "I own the game, and enjoyed it, so I have nothing to lose trying 2.0 when it comes out" but honestly not excited about it, and very little faith that they can actually turn it into a good game.
