A few weeks ago I decided I wanted to play through all the story missions and any side missions on the GTA games I own on PC. I'm working through them in reverse order because GTA V was the only one installed when I made the decision to play through them all. I finished all the missions on GTA V pretty quickly because I had 11 days off work when I was between jobs earlier in the month.
Last weekend I wasn't at home to be able to make a start on GTA IV, but I made it to the start of the missions on Algonquin this afternoon. Call me a nutter, but I prefer the driving physics on GTA IV, even though nearly everyone would say that they are too exagerated. Also, GTA V doesn't have the swing glitch, so there is that.
I'm planning on not buying any new games and will work through any old ones I would like to revisit, so early next year I can invest in a PS5 ready for GTA 6. Hopefully, GTA 6 will have driving physics somewhere between those on GTA IV and GTA V to offer a bit more of a challenge over GTA V.
