I pick TLAD and VCS over them. These two games are bombshells for me.
The Lost and Damnes is a well-written foil in my opinion, IMO despite being a 22 missions story or so (which is pretty successful enough compared to other GTA games which are generally around 60 missions and over). The protagonist, Johnny K, a real gritty, badass biker we'd like to see in my opinion. Having an antagonist like Billy against a badass like Johnny is even better. Bill is my favourite antagonist after Tenpenny. Look, Billy is the man. He's a sneak bastard with "above the bar" manipulative skills, he is a violent and wild guy, proper for a one percenter MC. I mean Billy is more to be likeable than to be hated, good thing. Having a best friend like Jim is over the top. I mean, Jim is more like a mentor figure for other brothers (John states that also), he's reasonable, integrative yet a hardened man. Story is quite impressive and enough.
Vice City Stories is one of my favourites right after IV. I don't know, people were generally disturbed about the story, but I did like it. Actually I couldn't like Vice City with VC, but VCS made me a bit high level more concerned with Vice City, and totally interested in Miami underground world. Coming to the story, it was quite impressive, I don't care what others say about it. Vic was a one tough nut, although in VC, he was a douchebag drug dealer (maybe Vic adapted himself in his business after Louise died, IDK. However, although I liked Vic, sometimes I think maybe Vic could make a perfect "dark" protagonist, by being a three-bit, cunning drug dealer, so this wouldn't form destructive confusions between VC and VCS in this matter of fact). Another good thing is with our noble Colombian drug lord Diaz. I think we could see much more of Diaz by VCS, I felt his solid characteristic much more better here. The missions were quite satisfying and joy, IMO. Also the empire building made the game more interesting, gave the player a more playing time.
Although, these two games were cool as ice, IMO, I will vote for VCS. It's more unforgettable and legendary for me.
