How much would I'd get for GTAIV? $40?
Sell on eBay, and you would get surprisingly close to the price you bought it for. Even more if you got some promo stuff, even throwing in a magazine with GTA IV on the cover, people on eBay tend to eat that stuff up.
Today I played a little bit, but this ridiculous pigeon shit is slow going for me. I have like 110 left, its like pulling teeth with this stuff. After I messed with that stuff, I went and got the one man gang achievement by keeping 6 stars for 5 minutes. It's pretty easy to get if you didn't get it at the start where you could do it by going over the blocked of bridge at the time. All you have to goto Playboy's mansion and go on to the computer to that pedo site, open it, instant 5 stars. Now go outside and gun guys out of the helicopters with an assault rifle, sniper rifle, rocket launcher, whatever. They'll come up the fire escape railing to and flank the other building and I gunned them down too to raise me to 6 stars, then just go back in and wait 5 minutes.
After I did that stuff, I went down the escape and stole that badass armored vehicle and they were shooting at me and it didn't do any damage to that beast. I drove it to the helipad and took off in a helicopter and still couldn't drop the 6 stars even with no one around because it follows you, so I took the helicopter to the highest building besides the empire state, and jumped off. Good shit.

Is there a way to get to the top of the empire state building?
