Man, I just read some reviews. I gotta say, even for $10,
I'm still not interested.

for $10 i'd but it. i doubt it will get any cheaper than that for a while....

At first I was like, "Yeah, I'd buy that.", but then I thought about it, I seriously doubt I would.

i bought it today in Tesco for £5. 
yes, that's right. 
£5.

There are too many other good games out there to waste time with Dark Void, even if it's only $10.

I picked it up from Gamefly for $8 last week. I've played two chapters so far and it's not a bad game at all. Not perfect by any means and it doesn't seem to realize its potential very well. Regardless I'm having fun with the game, messing around with the jetpack in tight spaces is hilarious and makes you feel like a badass sometimes.  Granted I was pretty in love with the concept before it came out. 
 
If you're looking for a breezy action game, at that price point its not a bad deal.
