I had to look up gameplay since I didn't even hear about this game, and it's way worse than I expected. I would have loved a remaster of the PS2 version that I was too scared to play as a child though.
I watch sometimes watch a couple of youtubers making a video game without talking to each other. Every one has just has something like 4 hours to work on the game, before passing it to the next deveoloper. And every game they produce in their 16 to 20 hours total looks better than this thing.
Doom 2 added few features and had almost identical graphics, copying many assets. It would be an easy list for any dev. Oh yeah, it also had some of the smartest and most skilled developers in gaming.
Though I would hesitate to count Fallout or Majora's Mask here because they were based on existing games, so the breadth of the work on things like mechanics had already been done, and they had the ability to re-use a lot of assets.
I don't know the extent of asset or code reuse for Vice City, so I can't really say if that should be counted the same or not.
Vice City was more like 18 months of development, some of which overlapped with GTA III. I suppose it helps to have a working game engine and an experienced development team who can iterate on something they're already made.
This is like saying that because you can write a sentence in one hour someone else should be able to write a trilogy of 1000 page books in an hour too.
