It's easy to think that a truly cross platform game that has Linux as a first class citizen would make a lot of stir. But I used to play Heroes of Newerth years ago when Linux support were way worse than today. I also read HN then.
I never saw any special treatment for that even tho I loved the game and it worked really, really good on linux.
Searching on algolia just proves my point: https://hn.algolia.com/?query=heroes%20of%20newerth&sort=byP...
I simply do not buy the story that just because you release it on Linux, have good linux support etc it will spread like wildfire.
S2Games, which made HoN, made a superior MOBA imo but none of my friends play it anymore. They play Dota2 tho. I think the reality of the situation is that no one cares about if a game run on linux or not except extreme nerds that would never use Windows and go through the daily struggle that is desktop Linux.
I used to be one of them, nowadays I only use Windows.
