I've always been a fan of trains, so making many little train networks in Train Valley 2 seemed right up my alley. I thought it would be like many other train games, about making a neat system that allows trains to efficiently run back-and-forth. Something like a simulation or automation kind of game. But oh boy, I was so wrong and disappointed.
Train Valley is instead a sort of action puzzle game, which is a combination of words I still never want to hear. You start with a limited amount of money, and your goal is to lay enough track with that money to get your trains running. There are different stations, each producing something, and most also consuming something, meaning resources need to be delivered there before they can produce anything. You gain extra money for each desired shipment delivered, and then use that to connect more places with trains, or buy more or better trains. You're graded on how fast you can satisfy all requirements, and how much money you have left over (plus some bonus tasks each level).
It sounds reasonable so far, but these train systems are terrible. Each station has a single point of entry, meaning only one train can come or go at a time. Further, with budget limitations as they are, and room being tight, there shall be no tracks which are traversed in only one direction. You are limited on trains and each is individually tracked, but they can freely teleport between stations. This really removed the illusion of any sort of travel being simulated.
Trains have no mind of their own, happily heading towards wrong stations and collisions. In fact, most of the game is not about what I described, but rather about the action part, which is managing these trains en-route. You have to keep an eye on every moving train as they approach each junction, and make sure the rails are going in the correct direction. The challenge is not solving a logistics puzzle, it's not being too slow at sending out trains while keeping an eye on all of them.
Needless to say, I hate it. I can't fault it for not being a simulation game, because that's my own oversight. But it's really bad for a puzzle game. The puzzle aspects are far too easy, and all the difficulty is concentrated in micromanaging trains. You can't even queue up actions, but sometimes have to intensely watch as a train reaches a station or crosses a junction to then send a new train or toggle the junction as soon as possible. I don't believe puzzle and action mix, and I wouldn't recommend this game to anyone.
