Sports games are a weak point on GOG
https://www.gog.com/games?sort=popularity&search=sports%20%7C%20racing&page=1 Most modern sports games are pretty much live services requiring an online connection which goes against DRM-free since they need to constantly phone a home server (plus micro-transactions) and retro sports games do need to have there licenses renewed if they were affiliated with any Leagues (Tecmo Bowl is an example were they had to remove all the player names when it was re-released so it comes down to if the publisher wants to put the effort into making those changes)/
Most are racing games but there are one or two soccer, baseball, or football games.
