Let me give you a basic maths lesson.

Killzone 2's sales are currently at 1.53 million. Last week, not counting Japan, it sold 27k units.

If it steadied at even 15k per week (I don't see why it can't do that), it would be at 2 million (470k away) in 32 weeks.

This is not counting Greatest Hits, not counting holiday seasons, and not counting the fact that it isn't steadying at 15k per week anytime soon.

You're acting like this game finds itself in a empty vacuum without any other (shooter) games around. Most of it's sellingpower has already been spend. I don't know how much but i doubt it will go over 2m.

I don't see how The Conduit being T-Rated makes any difference, to be honest. It's a letter, about four square centimetres large, on the front of the game's cover. That's the only difference. It's the same game, whether it's an M or a T. Uncharted was a T, which I find pretty surprising, given the high levels of violence, gore and swearing. Considering Dawn of War was an M...

You're forgetting that the conduit was designed to be t-rated, so it sells more. They looked at what sold and decided that it should have a t-rating. Something super niche like madworld was pretty much sold under the counter desk. The conduit will be in plain sight at most, if not all, stores. So it does matter.

It's still an FPS on a console which struggles to sell that genre; CoD:WaW will be lucky to get 2 million LT, and it's part of an established franchise. I can't see The Conduit doing more than 1.5 million, and even that's pretty optimistic. Killzone 2's sales will probably double those of The Conduit.

Just Like HV adopted the t-rating, they are planning a good promotioncampaign. They put some hard work in the game itself and are clearly smart enough to plan beyond that. Their last storytrailer had a lot of spark, certainly more then the examples you mention. Sega can market the hell out of that trailer alone. 

HV is putting their best in this. And time will tell, if it pays off. I give them at least a good chance.

Red Steel cracked a million because it was a launch title (little selection), advertising, and it seemed like it would utilize the Wii controls in a unique way. The game got mostly bad reviews so you can't say it sold because its a quality title. Call of Duty and Meroid sold well thanks to those already being popular franchises.

The only other FPS games on the Wii are Medal of Honor, Brothers in Arms, Far Cry, Quantum of Solace. All of which have had poor sales. Now take your advice and "stop spouting that bullshit."
