Things I'd want
- Motorcycles
- Agency helicopters (with no weapons)
- the ability to shoot out of vehicles you're driving
- more gangs
- larger city
- smarter civies and Peacekeepers
- fewer civies near gang bosses
- splitscreen
- online 4 player co-op
- boats (like sail boats and speed boats)
- more options for Keys to the City (assuming they do that again)
- the abillity to do Roof Top Races like Street Races (you know how you can just go straght to one from the main menu?)
- a map that show's you where you've found agility and hidden orbs
- more gang vs gang and gang vs peacekeeper battles
- the ability to go prone
- having a small (2-4) squad of peacekeepers/AI agents follow you (yes, I have played The Outfit; and I loved it :D)
- better online system (like that one guy said, it sucks how you have to restart the session whenever someone joins you)
Things I wouldn't Want
- tanks (come on, you're already a super powered weapon toting (sp) wicked awsome cop; a tank would take all the fun out of it)
- player vs player game type (kind of steers away from the theme of Crackdown, don't ya think?)
- more agility and hidden orbs (500 and 300 respectivly is plenty I think)
- mechs (it's not that far into the future; besides, same thing as the tank)
- vast terrain differences (if they base the sequel in a city, it wouldn't make sense to have a bunch of different terrain)
- destructable enviroments (again, it pulls away from the Crackdown feel; this isn't a war game)
- planes (the map would have to be pretty darn big for planes to be practical)
- a more futuristic time period (I think it's fine as it is)
- grappeling hooks (while this would make it much easier to get around, it would almost completely defeat the purpose of the agility skill)
- civies attacking you/setting up traps (there regular citizens living in a city ruled by gangs, and you're a super-powered cop; do the math)
- jet packs (see grappeling hook)
- giant mega-boss things (what is this, Star Wars?)
- higher skill peak (I suppose this one is just me being lazy; I don't really want to work that much harder to get maxed out, do you?)
- the ability to be one of the gang members (this would only work in deathmatch-type games, and I've already stated what I think of that)
- bases (supply points work just fine)
- must spawn at HQ after death (this defeats half the point of supply points)
- more vehicles with built-in weapons (3 is enough; again, this isn't a war game, not every vehicle has to have a weapon)
- secial abilities for agents (again, you're already a super-powered gang-killing super cop, you don't need bonus')
