V's heist mission was a goddamn joke. IV's bank robbery/heist mission was also a goddamn joke.
I expect missions of these types to have way more planning and 'prerequisites' to fulfill rather than show up and do it.
Good heist/bank robbery missions? Take a look at SA and VC. Those are well done missions & planning.
Vice City had well done planning?? The only plan Tommy had was "We go in the bank, we wave our guns around, and we leave very rich men" Doesn't seem like a well-thought out plan.
By planning, I meant the missions that led-up to the bank robbery:
Buying the Malibu club, recruiting Hilary King, Cam Jones and Phil Cassidy.
In Three Leaf Clover (IV) you were just thrown into it, which might make sense story wise but is no fun for the player. In V, it was too easy. Just picking your crew from a 'board' and stealing the necessary vehicles/equipment easily in under ~2 minutes.
