@To all who have never played Jak
Don't get your hopes. The Jak games were decent back in the day, but there were no Ratchet & Clank, or Sly Cooper for that matter. And after playing Jak 3 a few months ago, I must say, the games haven't aged well.
All I gotta say is Proceed with Caution. Check out some videos & reviewers before getting your hopes up too high.
