"It's frustrating, quite frankly. Certainly there have been mature titles - Resident Evil, the first Call of Duty - that have sold over a million units and with something like GTA, there's great content there. We do think it'll have a long tail and we've seen that with a lot of titles across all genres on the DS platform that consumers continue to discover them. par. But part of what's needed is you have to continue to put marketing support behind these titles. It's one of the things we've learned over the past few years. The old dynamic of throw it on TV for a few weeks and forget it isn't going to work, because new consumers are coming in all the time."    

Surely Rockstar must have seen these low sales numbers coming when they decided to make a throwback game like the original GTA games and not market it. Top down games' popularity died down long ago. Unless they do a marketing push i doubt that it will move big numbers on the PSP.
 
Well i guess not.

I'd love to see GTA: Miamitown Wars after they release GTA Vice City. The sales of GTA on GBA didn't stop them making this game, so I don't think the sales of Chinatown will stop them making the next top down GTA in future.

 @Rallier:
 
They do have an opportunity to advertise the DS version alongside the new PSP version, but to my knowledge, they're not. 
 
I think the PSP game will sell sufficiently, the platform has after all had great GTA in the past, games which have sold very well. If it's eventually made available via Go's network service, it will sell even better.    
 
 
...

The thing with this new generation, people need to know the game exists before it can actually sell. Just having the game out there on the shelves will not make it sell.

Advertising was practically non-existent for the game when it launched here in the UK also. All I saw was a solitary magazine ad in a games publication, no TV or street level advertising at all.  

I had GTA Chinatown wars.  Picked it up.  Held onto it for 3 months, then returned it.  Never even played it.
 
Edit: I hope that MILF statement is sarcastic.
