While the Nintendo DS has been putting up astounding sales figures since its release, Sony's PlayStation Portable hasn't enjoyed the same level of success. Industry site Gamasutra has taken a look at NPD sales figures, which were obtained from Game Informer, for both the PSP and DS. While we know the DS hardware is a much better seller, the DS also beats the PSP in number of games sold per system, although the news for developers may be somewhat more complex than these figures would suggest.
The report makes it clear that the DS has more games available, and those games sell better on average. Currently, the DS has seen 653 titles released, and these sell an average of 163,000 units per game. Meanwhile the PSP has been targeted by 396 titles, with an average of 133,000 units sold per release. Breaking that down, each DS owner has bought 4.8 games, while the PSP owner has purchased 4.2 titles.
The report also looked at the top five overall software sales for each platform, and again, the results put the Nintendo platform in the lead. But Nintendo's own games dominate the DS sales charts, with New Super Mario Bros., Mario Kart DS, and Pokemon Diamond at the top. The fifth-best selling DS game, Brain Age, sold more than Liberty City Stories, the best selling PSP game. There is good news for third-party publishers on the PSP, however, as none of the top five best-selling PSP titles come from Sony. Grand Theft Auto: Liberty City Stories leads the way on that platform.
On the PSP, only three titles have managed to sell over a million copies; in contrast, the DS has seen an astounding 20 different games sell at least a million units. Ars has broken down the hits on the DS and Nintendo Wii before—Nintendo has two systems that not only sell in huge amounts, but also move first-party games very efficiently.
Although no first-party titles cracked the PSP's top five, Rockstar games dominated the charts, taking three of the five spots with a pair of Grand Theft Auto games and Midnight Club 3: DUB Edition. The 5 best selling games on the PSP are also notable in that none of them are exclusive to the hardware. Games like Need For Speed: Most Wanted and Star Wars: Battlefront II have been ported to several different platforms, as have the Rockstar published titles.
While these numbers paint a very rosy picture for Nintendo and the DS, it is important to note that these figures only cover the American game sales market. While the PSP has struggled somewhat in the U.S., its sales have been skyrocketing in Japan over the last few months, thanks in no small part to the incredible success of the Monster Hunter franchise in that country. The trick may be looking at the PSP as its own console, instead of a home for ported content. DS games often look and feel very different than games on other platforms, while the PSP suffers from big-name games that offer little outside of lower quality graphics than the titles get on its console big-brothers.
