Man, is it just me or is Bastion always on sale? I'm getting a real sense of déjà vu here -- I really feel like I've written this story before. Regardless, Bastion is available on Steam for the low, low price of $5.99US. Also -- if you're feeling a bit wacky, you can also pick up The Elder Scrolls: Morrowind for $9.99.
I have to be completely honest -- I didn't really enjoy Bastion at all. I thought the presentation was stellar, and I loved the narrator, but the core gameplay? It just felt dull and repetitive to me. I really couldn't get into it at all.
I am very aware, however, that I'm completely in the minority here. I reckon the vast, vast majority of you will enjoy it.
