I played a single player game in easy mode just to give it a go. The map was set to reach 6000G, and I finished it in 45 mins. I took my time and did not speed things up. The AI makes little comments during their turn if you feel like reading them. Hard to say how much time it would have taken with the speed cranked and the stock market enabled, but a sub one hour game seems possible. I would have actually finished in around 30 mins, but made a bonehead move that sunk me about 2k, and had to recover.
There are a lot of curious unlocks besides characters. The Out For Lunch mode appears to put your character in AI mode, which you can setup (and unlock more it seems?) different strategies. Which seems nice if you are in an online game and need to go do something for a few mins. No need to hold everyone up. There is also a quick save, at least in single player mode, which is nice to see.
I also picked up a few things from the AI, for example as they noticed late in the TNT, if you get a straight sequence in the Ventures you get 30G after four which increases 10G with each step. So six in a row gives you 50G (my numbers may be off). This makes for a little bit of a mini-game of trying to string together big combinations while blocking opponents.
Getting the four suits and getting back to the bank as quickly as possible is pretty much the entire game in terms of introducing large gobs of new money into the pool. The quicker everyone levels up the more money is available to start undercutting, improving, and investing.
SO the size of the map and the amount of money required to win directly feeds into how long the game is going to take as if it takes 15-20 turns for people to make one loop, to introduce 1000G into the pool, and someone needs to reach 15,000G it is going to take A LOT of turns to finish. Compared to if the map takes 3-5 turns to do a loop, even if you need to reach 20,000G it will not take nearly as long. In short, looking at just how much money is needed to win is not the only indicator of how long a game will take.
This is Max. Capital, come in!
They never really figured out Max. Capital [MC] in the TNT, which was a big part of their grind. This number is the maximum amount you can invest into a property. When you land on your own property and get the opportunity to improve it? The maximum you can invest to improve it is your... MC. The more you improve a property the better its value and the more money you get when someone lands on it. Think Houses/Hotels in Monopoly with a cap.
The amount of properties you own in a district dictates how much your MC is. Example time. There are probably hard formulas here, so work with my vague examples and values.
You own the Sushi Shop in District A (REPRESENT!). Say your MC is 500G. You land on one of your properties, invest the full 500G to improve it and the worth of your shop goes up to 200G. That shop is now the best it is going to get, unless you get a good Venture card or someone invests (stock market) the worth of the shop is now maxed out. So you go around the board a few times and land on the spot next to it and purchase it. The MC for this shop and the Sushi shop goes up to 1000G, because you own two properties in the district, allowing you to improve them further and increasing how much you get when someone lands on it even more.
THIS is where the buyout starts to become really harsh. If you own two shops in a district and someone owns the third and will not sell it to you the game gives you the option to buy it out for 5x its worth. The only catch is you have to land on the spot.
These sorts of rules pique my interest as it addresses some of the bigger problems I have with Monopoly. In Monopoly a maxed out Boardwalk and Park Place is it. These are the best spots on the board. In Fortune Street any district has the capability of becoming the swank spot. The ways you can dick people and force buyouts throws some big swings, as we saw with Distract A in the TNT. You won't see this sort of thing happen in Monopoly unless the player themselves hits some bad luck where they need to mortgage their properties. You have some control in dismantling the big cheese in the game.
