I did like Johnny and Billy's dynamic in TLAD, but the rest of the cast could've used some work, they tried somewhat with Jim but in the end his death doesn't hit hard. It's odd, too, cause i remember one of the features there being that you can take different members with you in missions, they'd upgrade to better weapons the more you took them, and there's permadeath if they get rubbed off. Feels like they put the grounds for a load of characterization but forgot to add the characters themselves
TBOGT has it inverted though, the supporting cast is amazing, but Luis falls short as the protagonist himself, and like the cast of TLAD, there are some grounds in there, he has some backstory, can interact with his family, time in prison... But in the end it just feels like the dude is just there while the plot moves on and revolves around Tony and the rest of the secondary characters.
Know for sure very little fan tears would've been shed if it was Luis who got offed in 5 instead of Johnny
