It definitely wasn’t as good of a situation as it is now, but 10 years ago was actually pretty good for Linux gaming too. At that point Valve was already starting to support Linux and there were a bunch of native Linux releases for games at that time, including lots of indie titles in Humble Bundles and even a good chunk of AAA titles were getting Linux releases (e.g., Bioshock Infinite). If you had specific windows games you wanted to play you could very well have been out of luck, but there was actually a really solid number of native Linux ports at the time. I was personally pretty happy with it and just completely blew away my windows partition at that point. Of course you didn’t have access to the full catalog so to speak, but honestly you probably had access to more titles than on many consoles at the time, which arguably made it a viable gaming platform at the time (I made do with it!) Naturally, like any platform, you may or may not be okay with the selection of games available so it really depends on the person, but I was a pretty happy camper.
