Alpha Protocol also comes to mind. It was planned to be a franchise at one time. 

What is it with posters calling GT5 a bomb?

It's sales might be a little low in the Americas but it is not a bomb

If anyone thinks it's a bomb then your expectations were way to high

I expected DK sales to be a little higher but it is not a bomb

Now APB and FF14 are the poster boys  for bomb

there is only 1 bomb to rule them all.

the APB bomb.

Tony Hawk had the biggest bomb of the year imo

Started to tally up the votes, but failed.  Anyone else up to the task?  Who wins the VGchartz raspberry?

Ape Escape Fury! Fury!

APB

this one created his own category of bombing

Never even heard of APB - a serious question here: What the heck did they spend the $100,000,000 on? Seriously - what?

Enslaved, of course.  I don't understand how it could have gone so wrong for this "good" game.

Lords of shadow is dissapointing, but is another solid title.

And of course, Tron Evolution will be a complete disaster in sales.  Again, too bad.

I own all three games by the way.  Makes me wonder.
