I skipped GTA4 but I might give 5 a go, at least you know the scale of things and that you'll get a lot of gameplay out of it unless you get bored quick, heh.
It's also why I still play the Assassins Creed games, I know I'll get at least 40-50hrs worth from them and not some quick little 12hr thing.
GTA V was around 40 hours if you just did the story and most of the activities, i was at like 60 or 70 percent complete with almost 40 hours played.
Already finished it on 360 last year and haven't touched it since. The story was good up to the last hour or so. GTA IV was a lot better in that regard.
Still, I'll probably buy a complete edition one day on PC, when it's on sale for the DLC.
Same here, not double dunking or dipping etc. for me, will wait until it's $10 on Steam in a couple of years buhahahaha. And agree GTA IV had a much better story to my tastes. Relatable characters, a more sombre tone...GTA V went away from that, but was still very good.
