Frontier Developments, which creates video games, has signed two agreements with Atari Interactive, one for the publication of RollerCoaster Tycoon 3 (RCT3) on new formats and the other for the online distribution of the existing RCT3 and other Atari titles on PC and Mac platforms. The agreement, which is said to have formed part of its future e-commerce plans, gives the option for Frontier to develop and publish versions of the game for new formats and adds another title to its self-publishing portfolio. Chief Executive David Braben, said: "These agreements represent excellent progress as we continue to implement our self-publishing and on-line commerce plans. They will help accelerate our plans to grow new revenue streams from self-published and on-line commerce."NR
