According to video game site VG246,
LucasArts president Darrell Rodriguez has told GamesIndustry.biz that while no specific business model details have yet been announced for the forthcoming BioWare-developed MMO Star Wars: The Old Republic, a variety of options might be utilized – including subscriptions and micro-transactions – in order to appeal globally.
For those readers wondering, subscription is a business model currently used on Star Wars: Galaxies; you pay a monthly fee and you play the game. Micro-transaction means you pay for only the game itself and for whatever additional content you want. Normally it’s not needed for the game, but the balance for that in some MMOs makes it seem like those who pay for stuff have an advantage. We will have to wait and see, but having both would be very unique and interesting– a staple of both Bioware and Lucasarts.
