Note: An easy way to tell if people bought the game thinking it was fps, is to look at the second week sales of the games, after word of mouth gets to all those people who are looking to their friends to find out how awesome it is.

It would be difficult to say exactly what is a good dropoff rate, but a one tailed distribution test will help. If I have a feeling that the game was was mistaken, after looking at the second week sales, then I will do the math.

Works for me.  Others region 2nd week sales were 72k, a 47.7% drop from the 151k of opening week.  By comparison that's smaller than KZ2's percentage drop of 42.1%.  Not too shabby for the game people only bought because they were duped into thinking it was a shooter.

Killzone 2 is a shooter? I thought it was a survival horror game based on the adverts ;) 

Don't just randomly draw conlusions, if you're not going to use statistics to analyze it, then don't bother.
Just by looking at historical sales, first week sales should have been over 700k for a halo fps. So, it could be the case that people who bought the game knew what it was.
Anecdote: I did see a kid with an unopened copy yesterday who said he couldnt wait to shoot his friend, who also had a copy. I work right next to a gamestop fyi. And then another kid asked me if he should buy it, he was ~10 and saw me playing WoW so we talked about video games. I told him it was an rts, and explained what the was and he said it was stupid.

What's an "attach ratch"?

ya CGI, agree with you whole heartedly, But the bigger question is will YOU play Halo wars on the console instead of playing Company of Heroes on your two year old PC? :)

That aside congrats to Halo Wars: I have to say even I was tempted to play it on the 360. I also think that Ensemble did a superb job by making the story so strong (awesome cut scenes). I guess they decided to go back to the style of the RTSs of the 90s (Age of Empires, Command and Conquer, StarCraft) which were much more story driven then the extremely tactical and techincal RTSs of today. Hey come to think of it, I used to like that a lot!

lol we have quite a few noobs on this forum , KZ2 is clearly an RPG.

Wow thats amazing, a RTS that got decent reviews beats a hugely hyped FPS(with best graphics EVAR) that got amazing reviews, in a country that loves FPS's.
