I have joust on my home arcade machine and I love
the game.

Now that it is available to play over LIVE, what other
treats am I in for besides single and mutilplayer?
(I'm talking about the multiplayer that I'd experience by playing
on my machine with someone else.)

If that is all you can do, is to play a single game or a game over
LIVE with one other person.. I dont know if I want it... cause I can
do it already.

BUT... If there is a mode where you can have 8 other HUMAN opponents
flying around at one time, then this game could be very cool on LIVE.

Are there any fun things like this other than 1 or 2 player?

If gamerscore matters to you, then you might want to get it.

I played it when I was a kid. Can't say I've ever been a fan.

Gamerscore means crap to me.
I just want to know if there is crazy multiplayer action in the game
or if it is just the same old same old.

i got it free with xbox live. i never liked the game. i think its only 2 players.

okay. I'll stay away from it then.

i got it because i had extra points... pretty fun but noone is ever online in it...
