I know the topic makes me sound like a wuss but I can curse like a longshoreman with tourettes when provoked. It's just that this is...too much. The occasional f-bomb? Sure, ok. Need to season the dialogue a bit with garden variety profanity? Fine. But GTAV's writing is gratuitous and infantile. It ruins the experience. I get that this is supposed to be satire on some level - a caricature of our post-modern nihilistic, consumerist, kleptocracratic, dumbed down culture, etc. But this isn't even good satire. The writing is just atrocious. At least with some kind of profanity filter I could follow the mission plots without having to turn the volume completely down. Again, I don't mind some profanity in a game but this fast becomes nails on a chalkboard.
When GTAV hits PC I guarantee a profanity filter will be one of the earliest mods available, since I will create one.
Oh, and you're right. I probably should be more concerned about the game's objectification of women and its sadistic violence instead of some swear words. But you expect sex and violence in a GTA game. What you don't expect from Rockstar is entirely juvenile writing.
