As noted in my previous article on the subject, the new and improved Battle.net won't affect only StarCraft II -- among other things, the Real ID feature will allow you to see what other Blizzard games your real-life friends or acquaintances are playing, should they desire it. But that's apparently not the only perk for WoW players. Blizzard recently announced that migration of WoW accounts to Battle.net accounts will soon be mandatory, and posted a FAQ about it on the official website; one detail immediately caught my eye...
What will change in World of Warcraft after the forced migration?
The core gameplay experience will remain unchanged as a result of the migration. However, you'll be able to take part in all of the new Battle.net features, such as cross-realm, cross-faction, and cross-game chat.
That's right. Got a friend that plays Horde and you play Alliance? You'll be able to talk to them from inside WoW, even if they're on a different server. Heck, even if they're playing StarCraft II or Diablo 3, you'll still be able to chat with them. How cool is that?
To quell some concerns that'll surely get posted in the comments, the extent that others can utilize your Real ID is completely up to you. You decide who gets to see what information and to what extent -- if you want your best friend to be able to see what game you're playing or what server you're on, you can do that, but you can also prevent your annoying cousin from pestering you to play StarCraft II while you're raiding. No, Jeff, I actually can wait for you to "pwn" me. Gots to get me some purps.
