If you want to support the author, why not? DRM may be a performance buster, but you can always get a physical copy to support the further development and keep enjoying DRM-free content from the alternative means. Also for stuff where it’s harder to get something in an arrrrr way, physical media is often offered with steep discounts some time after the initial launch: I bought a lot of games for Xbox on disks for $10-15, while digital copies were still $60 a year after launch. BTW, if you have a game console, there is a good chance it has Blu Ray already.
