Okay so, about the game being completed and all that:
Point 1. I wouldn't call it completed when we have so many scenes without art.
Point 2. If you like the game, why on Earth would you want Majalis to stop making content for the game?
I agree with #1, but some people want to see the end of a story. A story can drone on, and on, and on, and on, and eventually just get old and boring to the point that the game is ruined. It isn't something like Paladins, where they can infinitely continue to add new characters, with new abilities, and keep people interested. This game seems more like a Mario Brothers type game, where you go through various different troubles to reach an end goal, and defeat the end boss, for a specific reason.
I have an empty folder marked "wait till finished/start over" because there's just so much that can be done with the game, and to me, it's a waste of time for me to download it every new update to se a couple bug fixes and maybe 1 new action/ability/level or some new artwork.
