A lot of good things have already been said here, so I won't repeat all of them. Is the game flashy? No. Will the graphics knock your socks off? No. Will you spend hours designing vehicles, getting the sliders just right, marketing it to a target audience, and strategically plan your dominance as a global car company (including taking over your competition!)? YES!

Here's the great thing about Gear City: you can put in as much micromanaging as you want or as little as you want. In general, I like to make more strategic decisions, so I let the AI run most of the company, and with Gear City, you can do that! Once I got the company established, and I was doing decently well, I just turned on "Auto Sell" and "Auto Produce" and "Auto Market". Voi la! I put some effort into designing the vehicles I want (and opening dealerships), and the AI takes care of the rest.

In fact, the AI is so good at it that I went from wobbling under somewhat profitable to all of a sudden making a boat load of cash! The AI knows how to optimize selling and producing, let me tell you! It wasn't very long into the game that I began making over $1 billion per month! Later in the game, I was regularly making $3+ billion per month, and I won an award saying I had finally made it to the same level as international car companies like Toyota, GM, et al.

It's challenging and fun. If you like sim-games, you'll like this one . . . . if you have a (at least somewhat) passion for cars.

It's very addictive. Min-maxing the different sliders and attempting to optimize different vehicles for different demographics is incredible fun.

My only complaints would be that some of the automation controls aren't automated enough. Factory output declines over time and you occasionally need to refurbish them. That's great, but after pressing the "refurbish" button, production isn't optimized and you have to go factory by factory, production line by production line, pressing a single button each time to recalculate car output. Simple things like this should have more automation. Also, as your company grows, lists of parts and engines become gargantuan-ly long. I wish there was some feature to group different parts & vehicles (into folders) so that it reduces the clutter.
