Seems that they dont like nintendo somehow.
I mean they didnt release gta3 on the gamecube before. They didnt do any effort when wii was the most selling console. And now when we do see that tieth party ports are selling that well on switch, it isnt that they dont like money?
Even there other port for switchwas based on a playstation engine with as low effort as possible which makes the game runs like s*
F them
Also there isnt something like nintendo audience. Gta 5 is mainstream as hell. Wii en switch are both bought by mainstream people.
Nintoddlers are an embarrassment

GTA Advance, and Chinatown Wars for the DS
Bully, Manhunt 2, and Table Tennis for the Wii
Chinatown Wars was real fuckin good too. God damn ninyenyearolds don't buy third party games and kill all hopes of a sequel.
Ninja Gaiden Dragon Sword is another exanple 

DS was the only Nintendo platform after the SNES with good 3rd party support and none of those babies supported it over lazy Pokemon cash-ins, at best buying piracy carts for everything else. Even a game with mass appeal like Chinatown flopped. So I'm pretty sure R* understands where their audience is. But noooo, it's always the fault of the secret conspiracy against their favorite shitty toy maker.
Not to mention, who the hell cares for
another GTAV port - unless you're such a manbaby, you refused to buy any of the dozen cheap-ass platforms that play that game

Nintenyearolds remain the most pathetic shills (though Gaben sluts are getting up there). bruh, voluntarily get the most limited gaming experience, while blaming everyone but your choice, or your beloved company, for it.
