"I've asked Jimmy Thomsen why buy Game Drift Linux and not
CrossOver Games and install it manually on Ubuntu, and he answered
In short: patches and price.
Cross Over won't work properly on Ubuntu (CodeWeaver is working on
a fix, we created our own since we couldn't wait). Another nice
difference is the price – you could download native Ubuntu
and buy CrossOver Games for about USD 40 – or just buy the
combined package (Game Drift Linux) for half that price.
