I must admit that, although I'm probably in the minority, I didn't care much for GTA4. Although I only rented it and played for 4-5 hours, I found myself playing the bowling mission and being bored, and by the time I actually got to a point where I could fight somebody, the combat controls were janky as hell. So I gave up. Some would surely say I didn't play it for long enough, but I play games to have FUN, and entertainment is not supposed to be work, so if I'm not having fun after 4-5 hours, I think that's long enough to throw in the towel.
The last GTA game I played before that was GTA3, and I remember that one being great, although it's been about 10 years since I played it. Anyway, just wanted to get everyone else's thoughts on GTA5 vs GTA4. If one didn't like GTA4, is GTA5 even worth bothering with?
