I've played Deus Ex (and the revision mod) and Splinter Cell: Chaos Theory on Linux without issue. If you're playing steam games it's basically just install and play. Especially for old games.
There's a website called protondb.com you can check for compatibility. Gaming on Linux is so good now though, I don't even check anymore before buying games.
Word of warning though. While modding games running through wine/proton is possible, mod managers don't usually work or are tedious to set up. I don't mod too much so I usually just manually install or stick with steam workshop mods.
Another nice way to visualize the area of fuel economy is just the cross section of the fuel hose going to the engine.
