I used to think, a long time ago in a galaxy far far away, that Rockstar couldn't do, or to be honest, shouldn't do another 80's game because there was nothing left to be done after VC. VC ends with
so to me the next logical step would for playing out
(no!) or playing as
(no!). Plus there wasn't any space for an additional storyline since VC takes place in 80's, SA in the 90's and III in the early 2000's. What, were you going to shoehorn a complete game between the end of VC but before SA?
But that was before it became clear that IV was set on a different timeline than III-VC-SA. So a new take on the 80's scene with 2022 gaming design capabilities could be...wow. I say go for it, lets go back to the 70's & 80's!
*And don't make fun of me for not spoiling a 20 year old game, I wouldn't want to spoil Se7en to a person who had never seen it before :P
