When I first got this, it crashed to desktop every other time I tried to start a mission, and 20 minutes into my first non-training mission it suddenly turned into a slideshow before the computer locked up entirely. However, after rebooting the PC, I have had no such issues. (However, with RadeonPro active I had to CTRL-ALT-DEL then Cancel to get the missions to start. Removing RadeonPro, all was well. That's an old third-party app anyway; I thought I'd give it a try.)

I had to assign the "Interact" control to a different key and use that in place of the instruction to click on a door with the mouse, as there is no mouse pointer when you're in walk mode. Without doing that, I couldn't get more than two minutes into the training mission, as it was impossible to close the cabin door from the outside.

I also found the automatic announcement system to be off by one station (I think I failed to use the "next station is closed" announcement when passing through a closed station), but when I tried to reprogram it at South Kensington, it still kept announcing "This is Gloucester Road" even though I'd just told it to start from South Kensington. Minor issue, since you should know to hit the "station closed" button before you reach the closed Blackfriars station.

Also, one of the early missions has some incorrect text, as it tells you to take over a train on Platform 4, when actually the train is on Platform 3. In general the English text is rather clunky; the developers are native German speakers and they didn't hire any native English speakers to work on their English translations.

It didn't seem to mind that I had forgotten to set the destination sign on the train in the first non-training mission. I've now finished a few missions. While there appears to be no scoring system whatsoever -- you either complete the mission or you don't -- in fact there is something happening in the background. In a mission where you have to make up time, at the end I was told I had achieved "59 of 60" and therefore failed, but nothing that explained what those numbers represent. When completing missions, it doesn't appear take all the details into account like the destination sign.

However, I just tried to do a non-mission "Drive to Schedule" run, and at the end, it did point out that I hadn't set the destination sign correctly (I had set it to the ending station, but apparently that's not right -- maybe it wants the basic "Circle Line"), and did in fact present a score of 72%. It mentioned braking too hard, going over the speed limit, and having the announcement system set wrong (which I did on the first station). So maybe that "59 of 60" in my failed mission means a score of 60% was necessary, even though mission completion screens don't give you any such score.

If you're not intimately familiar with the stations it can be difficult to know which way is east and which way is west sometimes. So when you have to take a train from High Street Kensington to Edgware end, you might take off and find the next station to be Gloucester instead of Notting Hill. I guess that's part of the challenge!

EDIT: In so doing the above mistake, I discovered that you can't actually collide with AI trains. When I found myself at the Gloucester Road station and realized I was going the wrong way, I reset the train to drive the opposite way and found myself head-on with another train that was stopped waiting for me. I figured the mission was over and decided slowly to bump into the AI train head-on... but I ended up driving straight through it and actually was able to complete the mission despite my detour.

Anyway, I am quite enjoying it. The detail is really nice. You have to (or rather, can) switch everything -- right down to the heating and ventilation systems for the passengers. (The windows even fog up if you don't turn the ventilation on, during certain times of night and weather conditions.) It doesn't have any complaint system from passengers like Bus Simulator 16 for example, though, at first glance or when doing missions, but in Drive to Schedule mode it does point out if you were braking too hard, so that counts as a passenger complaint.

If you want to slack off from your mission you can just hop onto any of the AI trains and take a ride as a passenger! That's pretty cool.

The riding of AI trains is part of the normal gameplay too. Some of your missions require you to hop onto a train to a particular station in order to take over control of another train at that station. Really nice feature! (As long as you know which way is east and which way is west so you get on a train in the correct direction!) The map included with the game is the entire Underground system; downloading a specific Circle Line map from the internet is highly recommended -- just make sure you get one from the 2009 expansion of the line, and make a note on it to yourself about Blackfriars being closed (for it was when this game was made), so you know when to hit the "next station is closed" button on the announcement computer in order to keep your announcements in synch (not that the game really cares if your announcements are correct, or even used at all; this game is very much a self-policing sim except in cases of speeding, running red lights or derailment (if derailment is turned on in options)).

So, as a simulation game, I do recommend it, despite all the crashes and the system lockup I experienced initially. Maybe my CPU or GPU was starting to overheat or something. I know many people have no such worries so I can't fault it too much -- just be aware that it may not be particularly stable for you, but try rebooting after installation, as that seems to have cured it for me. (It's using some sort of nVidia-branded engine, so it could be that it doesn't play nicely with ATI graphics cards.)

In terms of graphics settings, it has no anti-aliasing, so you might want to force your graphics card to provide that if you can handle the frame rate. The "Glow" option is HDR glow which is really horrible -- causing complete whiteout on a lot of signs. I found it looks much better with the Glow turned off. It does provide an anisotropic filtering slider, a selection of shadow qualities, the ability to turn off bump mapping, reflections, a simpler lighting system, etc., so there's a fair bit of optimization you can do if your frame rates suffer. I keep most things on max (shadows to Medium, Depth-of-Field Blur off and Motion Blur off), and manage 30 to 45 fps on average with my ATI R9 270, which is all right since you're never going over 40 mph.
