A short game isn't necesarily bad, and I think the last few years have shown that lenght has little to do with quality. I can list a ton of games with less than 10 hours of gameplay for a single playthrough that I consider to be amazing, and I can fully agree with the core idea of preffering to play an amazing 8 hours long game than a mediocre 40 hours long game.
But I think value is also important in a game and personally I'm just not seeing much value in The Order.
Bayonetta 2 is also less than 10 hours long, but offers so much replay value in the form of great difficulty settings, extra challenges, unlockables and bonus content that in the end I spend over 30 hours on this game (and that's not even considering that it also had a fairly fun multiplayer mode and came with an enchanced port of the first one). To me it felt well worth the $60.
The Order 1886, from what I've read ever since all the early impressions have started to come out, sounds like a game I'd beat once in less than 10 hours and then I would move on to something else. It seems to have little in terms of replay value other than collectables which I don't care about, and unless a videogame offers different dialog paths and choices (like mass effect) unskippable cutscenes are a real replay value killer for me.
That doesn't make The Order a bad game or aything, it just makes it a game I will feel more confortable buying for $30 or less. It's an ideal rental game but, sadly, I don't have videogame rental places in my area
