What order should the 90s Wolfenstein series be played?

In what order should the 90s Wolfenstein series be played? I use to think that Spear of Destiny should be played first since it is a prequel, but now I think this is not the case. Wolfenstein 3D can be played first. Then Spear of Destiny can be played. Did Wolfenstein 3D episodes 4-6 come before Spear of Destiny was made? Spear of Destiny still could be played first, then Wolfenstein 3D episodes 4-6 could be played, then episodes 1-3 in order to play Wolfenstein games in chronological order. I think playing Wolfenstein 3D episode 1, episode 2, episode 3, episode 4, episode 5, and episode 6 and Spear of Destiny will work. Wolfenstein 3D episodes 4, 5, and 6, and Spear of Destiny is simply a flashback to BJ's earlier adventures. Also, episode 6 is an epilogue to the 90s Wolfenstein series. It tells the future story of BJ's life.

Wolf3d first, then Spear of Destiny...End of the discussion.
