I again think hint 43 should be removed. I get it, linux is great and all. I use linux as my primary development environment. I took a class that specialized in linux. That line still sounds elitist, immature, and unprofessional. It even completely misuses the period character (an ellipse is three periods, and represents trailing off thought or momentary pause; two periods is meaningless). Never mind the stupid smiley face on the end.
And to be honest, hints like number 44 are completely fluff. It doesn't help a player new to the game at all.
To be brutally honest, though, I think most of these hints are pretty useless. The global hints is the wrong approach. Hint should be stored with the faction, so advice that is actually relevant to the player's expected play style can be displayed, not useless generic information like "upgrades are important" and various hotkey stuff. Instead, we should be telling players specific ways to use units, specific upgrades, etc. But in order for that to be useful, hints need to be delivered by the faction (ideally overwriting global hints).
