SimCity, top this.
Some enterprising Microsoft Flight Simulator users have released a third party scenery package for Manhattan that rivals anything in the private sector, anyway, for fidelity and jaw-dropping realism. Having flown into Manhattan a bunch recently on business, I thought I'd see what was out there to enhance the look of the city from the somewhat blah default scenery Microsoft ships with FS2004; I wondered if someone else had rendered the city with all of its famous landmarks so that a VFR pilot like myself could take a realistic sightseeing trip out of LaGuardia on the ole PC simulator.
POW! I cannot believe the level of detail this team has lavished on the Big Apple. I mean, you could run an entire hour of SimLaw & Order (complete with opening credits Lennyism) on the ground here, by the looks of it. The only drawback I could imagine is that this is a massive framerate killer and might take a 3GHz box with the $400 video card to run at all smoothly.
Bottom Line: If you don't care about simulators, flight or otherwise, I still think you'll be impressed by the attention to detail.
