Been a long time since I played 4. I thought they were similar, but in 5 there's 3 different characters and a much more diverse and entertaining storyline.
I honestly think there's not much to split the graphics - but 5 has a better map with loads more vehicles etc.
What it is about 4 you like better?
Well when I first played it the mechanics and graphics etc blew me a way it was next level. But I also enjoyed the dark serious tone and Niko Belic was intense and had a interesting back story. Loved the grit n all.
Don’t get me wrong love when rockstar get over the top and silly like in 5 but I was expecting a lot more. I figured if it wasn’t going to be a major leap then atleast the story was going to be insanely big. When I did the last mission I thought to myself ‘now we are talking let’s see we’re this goes’ I thought the game was just getting started and then the credits rolled. I was in shock.
Also there’s a video out that actually gets into how 5 decreased insome physics, animations and graphics (insome areas) like 4 took more time with the smaller details. And it clarified what I was subconsciously feeling at the time but didn’t wanna accept it.
I think 5 plan was the online mode and more effort went into that to the detriment of the single player.
