At release, the game suffered from a series of reoccurring bugs, particularly on PC, which can seriously affect gameplay, and which prompted the studio to disable the multiplayer functionality due to connection and server issues. General issues included: server blackouts, repeatedly dropped connections, inability to add friends in-game, and many other advertised online features malfunctioning or not functioning at all. Several patches have been released to resolve the issues, as well as several free or fee-based downloadable content packages and individual items (i.e., new missions, cars). The initial download is free but the virtual vehicles carry a real-world cost in the form of in-game 'tokens' obtainable for real money. For the PC version of the game, the price was set at 80 Atari tokens each, and the smallest amount of 'Atari tokens' available for purchase is a bundle of 400 tokens for US$5.
