Is there a method to get 3 accounts to join the game of my primary? Or does this require a bot?

yes

type game name with your hands

Guys a friggin genius.

If you can get the games going, you can join. Install the game X times and that's it.

LOL

he answered your question you need to do it manually or use a bot lol

thats what i was afraid of. i won't give in to that madness. guess the old fashioned click copy paste it is..

yes

but in order to "copy" something, you need to "create" this "something" first

now you can read #2 again

not sure what else you expected as an answer, your question is pretty simple

i can run two d2’s with two comps. Never had to run three, so maybe just use 3 comps.

You can create 3 instances of diablo (3 installations and 6 keys) and run it on the same computer. If you you use sandboxie you have your "virtual computer" in an extra window and you can start the second copy and so on. It is permitted by Blizzard this way. The free version of sandboxie just supports one running instance tho.
