Alrighty, I'm now 6 hours into the game and I only JUST got out of the first part of the map.
This is pretty much the whole map, and you spend the first 6 hours in the part in the upper left corner, which is, frankly, too long. It's not like I did much besides the missions either. Speaking of missions, so far they've been mostly tutorial-y stuff that are mostly just there to introduce you to all the stuff you can do in the game. I don't mind, cause the core gameplay is good enough that it's entertaining, but it could do with one or two more big, memorable set-piece-heavy missions. Remarkably little focus on combat so far as well. I think I've only been in 2 or 3 shootouts so far.
I do love the look and feel of the game. Disregard my complaints about the cops and the camera above, I quickly got used to the controls and have managed to outrun the cops in all my run-ins with them since the disasterous first attempt. The wanted system is one I haven't seen the likes of since Driver:Parallel Lines. Basically there are different wanted-meters for you and your car. So if the cops are on the lookout for your car, you can ditch it when noone's looking and be in the clear. Likewise if you're wanted on-foot, you'll be in the clear if you manage to get into a new car without anyone noticing. It works really well and I wish more GTA-alikes did it like this. I'd even say the game is too easy, as I've only died twice in my 6 hours with it. I also feel like I've unlocked most of the significant upgrades and I'd guess I'm only a third of the way through yet.
Overall tho, yeah, it's good stuff!
