SimonG: It's pretty much like
The Matrix. Also extreme cliffhanger ending, but it is enjoyable on its own.
(If only there were no sequels...) gameon: I actually liked matrix reloaded, it was revelations that made me cringe.
There were no sequels to The Matrix. It would have been interesting to see how it would have continued, but in a way I'm glad that they never made one. Sometimes no sequel is better than a bad sequel, and I would not want anything to tarnish my good memory of The Matrix (even if I find the movie to be a bit overrated).
Anyway, not played Enclave, but Advent Rising was an enjoyable game. The story was really good, and the soundtrack was outstanding. Horrible cliffhanger ending though (as others pointed out) and no sequel :(
On the other hand, I'm not all that fond of Orson Scott Card, due to his opinion on homosexuals, so I don't know if I would actually want him to have the extra money that another game would bring...
