You can keep your Batmans and your Deadpools: I want another Hulk game. He doesn't need the dark, emotional veneer that's been painted over Batman, just a big city to leap over and smash into rubble.
We've been starved of good Hulk games since Ultimate Destruction from 2005, but one enterprising modder has worked to get Marvel's big green hunk into GTA 5. It's clunky but awesome (sort of like The Hulk himself, no?).
JulioNIB's Hulk Script mod does an awesome job of giving you Hulk-like powers. You can leap over buildings, punch people a good 15 metres, tear up lamp posts and swing them at the people of Los Santos. Best of all is the ground-pound. It looks excellent in GTA 5, blasting out a wave of dust and rubble.
With the size of Los Santos and all the systems of fleeing civilians and escalating police, it makes for a Hulk game that's more complex, reactive, and looks better than actual Hulk games.
If you want to wreak destruction on Rockstar's city, you can download The Hulk Script for yourself.
