I was a huge fan of the first Crackdown (I'd have given it a 90+(?)/100) at the time. I'm a few hours into Crackdown 3 and I'm loving it. It's vastly better than Crackdown 2 (which is, obnoxiously, scoring higher on Metacritic as I type this). What I've played so far of CD3, I'd score around an 85/100. Exploring the city, leveling up, experimenting with weapons and vehicles, and pretty visuals are all well done. It absolutely stands up to the original and is a worthy successor.
CD3 bypasses the original with some of its features like enemy variety, weapon variety (with great sound effects), increased traversal options with suit boosters (very fun to use), a really useful/cool 3d map of the whole city you can rotate and zoom in and out of, a far more fleshed out story with better characters, some nice CG and cool cook comic cutscenes, and I'm just getting started.
It's a a big, loud, comic book third-person open world Crackdown with next-gen colorful graphics and a light sense of humor. I really like it so far and can't wait to sink more time into it. If this game scores sub 70/100, that's criminal.
