See the linked article for a list of the supported games.
Blizzard games are of course included, but we also get:
- Avowed
 - Tony Hawk’s Pro Skater 3+4
 - DOOM: The Dark Ages
 - Sea of Thieves
 - Crash Bandicoot™ 4: It’s About Time
 
If you need help on installing Battle.net, gamingonlinux coincidentally just published an article on getting it installed.
You can also use Non-steam launchers



Here’s instructions on using lutris or installing directly through steam
The easiest way (imo) is probably to use Non-steam launchers
I use Lutris for a couple other things, so I’ll try that.
Thanks!
