According to an interview at GamesTM.co.uk, Star Wars: The Old Republic's Lead Designer Emmanuel Lusinchi lets it be known that the BioWare team has considered a free to play model to keep the game competitive with the tide of other F2P games on the market today.
“I think it’s more than the free-to-play model – it’s more that there is a lot of competitive offers,” suggests Lusinchi. “If it was just free-to-play games and they weren’t very good it wouldn’t even be a question but there are definitely good games out there and good games coming out, so of course all of this competition impacts your plan with what you want to do.”
The small article is a teaser for a larger in-print interview scheduled to arrive in July.
