Square is delisting The Last Remnant for unknown reasons. In other words, you won't be able to buy it on Steam after September 4th. If you've already bought it, you're fine, but for some mysterious reason they're pulling it. I don't understand why they would do that... They're digital copies, they don't have to continue manufacturing it, why would they do that?
I'm baffled because although it didn't sell well and has no shortage of flaws (some inexcusable), I love that game and have played it many times. The battle system is incredible imo, the music and graphics are wonderful. The dialogue and voice acting has problems and the story is... well, passable, but there's nothing so bad that requires its removal from the market.
It's $10 on Steam. Please give it a purchase if you have never played it. It's very frustrating at times and has a lot of problems but the battle system makes it worth checking out especially for $10.
