I just started playing Black Mesa, and just recently got Half-Life 2 in Steam (I know I'm very late to the party).
I would like to ask a question regarding stealth elements about those two games. (I am thinking the answer will be pretty much the same for both. If not, I guess the difference can be stated.)
My question has been posted here (initially tagged with black-mesa only): What stealth elements are in Black Mesa and how does the enemy AI detect the player?
Since both are related (Black Mesa is a modification of the Source game engine, a game engine introduced by Half-Life 2, so therefore, they could have similar gameplay features and quirks) and have similar gameplay elements (both are in the same vein as the original Half-Life), is it acceptable to ask this in one question and just tag it with both black-mesa and half-life-2? Or should I ask the same question for each game, with one game tag per question?
Edit: I eventually just posted another question with the half-life-2 tag here: What stealth elements are in Half-Life 2 and how does the enemy AI detect the player?
