I've been sick for the past couple days. This has pretty much sequestered me to my bed, which fortunately for me, is in the same room as my 360. I've gotten a good four hours into Shadow Complex and have had a relatively good time doing so.
Shadow Complex is based on the Super Metroid blueprint and the developers make no effort to hide their inspiration. There is even a subtle musical nod to the SNES classic in one of the levels. And while Epic Games put a ton of effort into letting Shadow Complex sing its own song, there's just something missing...it doesn't resonate the way Super Metroid does. I don't find myself thinking about the world after I turn it off, or humming the tunes from the game. It lacks that indefinable "sticky-ness" that so few games from this generation are able to achieve.
That's not to say I don't like it. It's certainly a finely crafted experience. It just fails to live up to its inspiration.
