I say obviously, despite not having played any of Vice City. GTA is obviously at its best when you're just larking about with trucks and drawbridges, so I wouldn't worry. Here's a trailer, which confusingly features remade cutscenes from Vice City's singleplayer campaign that you can't play with the mod - you only get to muck about with the map, and some homemade missions. It started life as a makeover mod for the original Vice City, so in theory its a better version even before GTA V's technobits.
The mod's been floating about for years but only recently hit version 1.0. Sometimes, those cities are sucked from 2002 and splatted into modern videogames, like the Vice Cry: Remastered mod that takes the Grand Theft Auto: Vice City map and plops it into Grand Theft Auto V. There's always a man, a lighthouse, and a city.
