Guys,I found way how to play as guest.You can give to your friend to try playing Order vs Bots(AIs)[Computer].So this is how it works:

#1 Get some replay link and watch it on that link(not on SE).
#2 When it load,press quit game before match on replay end(Picture Number 1).

#3(1/2) When you quit,you will see that "menu" from the game and some part from normal SE lobby(Picture Number 2).

(2/2) Press "Leaderboard" button,Then "Lobby" button(Picture Number 3).

THANKS FOR READING THIS!!!!!

It shows "Myself" even if you're logged in.

Doesn't it show your username IIRC?

No. It shows "Myself" and "[difficulty] [race] AI"

As long as you can't go ranked on this, I'm okay with it. But seems like a hassle to do this, no?

Considering you have to log into an account to acquire the replay.... yes.

It takes no time flat to make your own SE account, and if the issue is letting him play on your account is risky... simply don't. Just use the campaign that's much better than the online AI anyway.
