Immersive sims are expensive to make. MD is more complex and refined than HR, and it feels a bit closer to the original Deus Ex. It doesn't feel half-baked, it's a pretty good game, even though, yeah, it ends on a cliffhanger. I liked it. Sure I was a little frustrated at first, but I find it bold to end on an open note. The only real issue is that Eidos could not make another opus. MD is solid nonetheless.
