I guess you should try to see if you like it.
I can't. I don't have the game, or a computer that could run it. I wasn't asking the question for my own benefit - the grading depends on whether the game's SP mode counts or not.
Let me rephrase the question. In previous UT's, the singleplayer mode does not count. In all of the CoD's, the singleplayer mode does count. Should the SP mode count in UT3?
I guess I have one other question. In multiplayer mode, does using the mutator restrict you in any ways? That is, are there any ways you can play UT3 without FreeFOV enabled that you cannot with FreeFOV enabled? Does it conflict with any of the game's built-in or popular gameplay modes or other mutators? Is it friendly with all of them?
Basically, I'm trying to determine whether or not the FreeFOV should be considered the "official" WSGF solution or not. I'm thinking yes, but I can't be 100% sure without playing the game myself. That's why I'm asking a lot of questions to you, who have played it.
