Tempted by GTA V but I've had GTA IV for ages and never really played it.
For what it's worth I was in the same boat, had GTA IV for years and never got that into it. Not sure why but something about it just felt clunky or whatever and didn't grab me. Recently bought V and I'm loving it. I think I'm as far if not further into it than I got in IV already and that's with less time to play these days.
I know it's just my opinion but I'd say if it's at a price you're comfortable with then it's worth a shot
