I do not know about you, but the PSP just delivers better graphics than DS. I have always believed that PSP is a better portable machine. Not just in the graphics department. But comparing other factors too, like better exclusives. Here is just a good example of why PSP is way better. Grand Theft Auto: Chinatown Wars, both available for the PSP and DS. Which do you like more?
If you look on the web for opinions about which one being better, most will either say something like: "they are both good in a way, or they both have advantages and disadvantages". I am so tired of that neutral crap, and I think that they are all bound to say nothing against either handheld because they do not know much about video games, because they are not even gamers themselves.
Sony is certainly not giving me a cent for saying this, and I know about both consoles. I should just say that PSP is the best handheld gaming device there is. If you think about it. Sure you can get a DS for much cheaper than a PSP. You are certainly paying what its worth. For reals, sorry DS fanboys, I have to say it. Now it has been on my mind that since the release of both consoles one was more design for kids(Nintendo DS) and the other for a more grown up audience(PSP). That is how I see it.
Just look at the DS ugly pixelated screen. Those graphics are probably a decade old and even though the game is new release by the looks of the DS seem outdated.
