Which Star Wars game series is the most successful?

As always, I'm voting for Knights of the Old Republic – this series is the most pleasing to the eye and mind... the ability to think and choose extensively... The only thing that Jedi Outcast and Jedi Academy offer is enjoyable gameplay... it's almost pleasant to slash and dice... But for everyone else, Knights of the Old Republic is the best – if only we could combine the best qualities of both, it would be perfect.
