I know, it's an unsatisfying answer. But there's no technical reason why you couldn't. I think the default is ~/games/whatevername and you're free to install games to any mounted file system.
Personally, for my entertainment, I like being able to just back up my home directory and not think too much about or keep track of other places my stuff can be. Is this efficient? Probably not, but sometimes a decrease in cognitive load for years to come is worth the 1 or 2% reduction in gaming performance from sharing drive bandwidth with your OS today.
It's up to you.
