I bought this as I read that it was a game similar to Majesty: The Fantasy Kingdom Sim, one of my all-time favorite games.
And after getting the true ending achievement, don't waste your time or money with it.
It is Majesty gameplay wise and I do like the set-up of the world, which takes place on a planet that was literally blown apart by wizards and the remnants of civilization are living on islands floating in the stratosphere. And said wizards still exist and can use their powers to create new islands, move existing ones closer to their base and even blow up enemy islands. It's a cool premise that is letdown in every way by the game itself.
It is exceptionally mediocre in every way. The music and the sound effects are very generic (although I didn't hear any of it as I was having headset issues at the time), the story has NO voice acting and is told through massive text boxes, all the factions have the bare minimum changes to not be copy-pastes of each other, and the graphics are decent, they suffer from the weird washed-out 3D look that modern 3D game developers overuse because they didn't ask anyone if it looked good. And while the gameplay loop of Majesty has it's flaws, it made up for it with the charm and vibrant nature of the setting that Driftland has none of.
This game is so not worth it that I always feel obliged to warn people about it. Not the worst thing I've played but you're better off with other games, which is a massive shame at the end of the day.
