That's because you're uneducated and foolish. Jackstain IRL probably couldn't handle a lightsaber any better than Alf's fleshsaber because he's as Force sensitive as cooling pile of crap. (No offense to my esteemed colleague. Buff Bagwell... where'd you get that?..)
Maul would be a nonentity in this fight alone against Revan, and adding Jackstain, unless he was a Force master which ain't the case, is a bit like sending Barney Fief up against the Predator.
And back to the game...
This is what would really happen:
jackstain: "Oh my god it's Darth Maul! You're my favorite Star Wars character! Can you sign my toy Maul lightsaber?"
*Darth Maul inserts lightsaber through jackstain's stomach*
jackstain: "Oww, that's ok, you're still the best!"
*Revan laughs so hard it creates a Force wave and blows Darth Maul off a cliff.*
heh heh. Just kidding jackstain.
