Only a few probably noticed its absence, but Yar's Revenge was de-listed last month with no explanation. Lots of xbla titles have been de-listed recently with shutdowns and license expirations. In what seems to be a possible permanent price drop the game is going for 400 msp right now. Or it could be a re-listing sale. $5 seems reasonable for what it is. I remember enjoying the Quick Look so I'm going to jump on it before its gone again just in case.

Also, does it bother anyone else that they shifted the apostrophe from the original 2600 Yars' Revenge? WHY ugh.

I have 400 msp burning a hole in my pocket, and the only other XBLA game on sale that I don't have and looks weird/fun is Zeno Clash. I'll probably go with Yar's simply for the fact it seems like Sin and Punishment. Star Successor is a blast on the Wii.

I hadn't realized it was de-listed before today, though I assumed that re-listing was the case after seeing it in the new releases.

$5 is a good price. I quite enjoyed that game.

The reboot looked awful and did not remind me of Yars' Revenge 
They didn't even seem to get that it was the revenge of Yars not the revenge of Yar 
Meh. 
They probably would've done better to make something more in line with the original game but with some cool twist (like those crazy pac man games did). Probably would've cost less to make too. That is speculation though.

@CornBREDX: The game is totally pulling on my liking of Sin and Punishment not Yars'. Besides the look of the shield, they having nothing to do with one another it seems. Honestly Atari could of slapped any name on this game that wasn't a call back. The reference is lost on new players, and upsets those who played the original. I totally get you.

I think Zeno Clash is legitimately a better game than Yars' Revenge.
