I've never played an MMO. Defiance is my first attempt at the genre, please answer as much as you can. I read somewhere that this can be played solo, and I am intending on playing it on solo as much as the game permits.
1) Can Defiance be played solo as a straightforward 3rd-person shooter with a story, with a beginning and an end?
2) Please explain the allure of MMO's in general and Defiance specifically. What is it about MMO's that make them so addicting? For MMO veterans, what about Defiance is groundbreaking and you are most looking forward to?
3) Also please explain in detail PvP and PvE and free to play and their implications.
Thanks in advance.
