wine is not an viable option. it's a bad workaround at best. updates will constantly break games. performance and quality is often much worse. many effects are not supported yet and probably never will be. it might not be true for dos NOW but it's true for many titles out there that worked and then suddenly stopped working.
well i was pretty lucky so far, probably because i usually wait for the finished version (with all DLCs/Expansions). But a native version is certainly better & i look forward to see more games running natively on linux. Fortunately, linux support seems to get more common, at least in kickstarted / unity games, maybe even in future AAA-Titles due to steamOS.
