Criticism
The company has been criticized for their unclear publishing methods particularly regarding niche Japanese titles; the PAL-versions of Ar tonelico: Melody of Elemia, Raw Danger! and Fire Pro Wrestling Returns for example are officially released, but seem to have seen such a limited release only in France and Italy that many people are unsure of their very existence. Wild Arms 5 on the other hand has been announced at first for 30 November 2007, then been delayed until 22 February 2008, only to be released on 11 April 2008 in such limited quantities as the before mentioned games. Its predecessor Wild Arms 4 was also published by 505 Games, but suffered from a bug that would make the game crash if played in 50 Hz-mode. In early 2010, 505 Games has been criticized by customers for failing to release a game-fixing patch for the Xbox 360 version of IL-2 Sturmovik: Birds of Prey, even though the same patch was released for the PS3 version. Comments by the developers of IL-2 Sturmovik: Birds of Prey reveal that the patch has reportedly been finished, but has been sitting in limbo for months awaiting approval. This approval delay was most likely a result of the 1st party Microsoft approval process for updates and bug-fixes. This company is currently attempting to release Terraria on PS3, even though 505 Games released Terraria on it's release date, it ended up being half broken. 505 Games is currently working "every Possible hour" into fixing the game as soon as possible, as this was quoted by 505 Games on the Terraria Forums.
