Is there any way to have games I already have on my computer listed on my Steam account?

You can add a shortcut to other games in the Steam client. Some games come with Steam keys (like the retail version of the Divinity Anthology[www.divinityanthology.com]) or CD keys that can be registered on Steam.

I've had this game pretty much since it came out, so no Steam key (no Steam then lol). Thanks for the user tip :)
