I'm not a big fan of the concept of 3 persons (4 with multi), but it's done and it's sometimes very interesting (mission several characters, stories that intersect ...). I'll just have preferred a more common progression (including properties).
GTA 4 has totally revolutionized graphics GTA, GTA 5 still improves while restoring many missing content in the 4.
Alas, some extras are still missing (fire missions, ambulances, for example).
What is very unfortunate is that cars almost deform during collisions, resulting in a loss of realism at this level compared to GTA 4.
