Carrying on from the discussion in the main thread I felt the characterisation was quite poor, the only characters I looked forward to doing missions with were Bonnie (real shame that her bit at the beginning was awesome and then you don't see or here from her for ages, that was what I like about GTA4, it never felt like the characters just disappeared when you weren't doing their missions) and the old gunslinger guy in Mexico (although his name escapes me)
I really enjoyed the bit at the end with your family, I wish more of the game had been like that and the early Bonnie missions. I enjoyed stuff like the cattle herding because it felt like it wasn't something I'd done before.
