This game is being made for the Nintendo DS, not the Gameboy. That's like calling a PS3 the same thing as a Playstation. Same company, huge difference.
But I get the point of what you're saying. I think it makes more sense to buy this game if you already own a DS. Wayforward has already admitted can be completed in a day by experienced gamers...I don't think there is enough going on with Aliens Infestation that would warrant or justify an entire purchase of a new Nintendo DS (even though some people will do just that).
I would understand it more if this was 1994 and Aliens vs Predator had just come out for the Atari Jaguar. Until that point nobody had ever seen a proper Aliens-based fps. Haha...it probably would've been the only Jaguar game I would've owned too. But in 2011 there has been a stream of 2D/3D games based on Aliens that have hit the console market since the 1990s, making this one look more run-of-the-mill to the average gamer.
Thankfully, I bought my DS back in 2006. Infestation just gives me a reason to dust it off and play another cool game for the system.
