As a brand new Train Sim player, I'm realising one thing quickly. This game is expensive. I mean seriously expensive. Long term players may not realise it, as you collect assets over time, but as a beginner, let me explain. What actually made me want to play TS in the first place was the Armstrong Powerhouse Class 40 loco add on. I think it's superb, and although I can buy it, and drive it for £19.99, if I want to use the scenarios with this pack, then the total cost becomes £134.64, as being a new player, I have none of the required assets to run the scenarios. I guess this game is a long term commitment that requires careful planning of additions.. almost a game in itself. LOL How deep have some of you gone? I suppose I'm a casual player compared to some, but just curious... how deep does the obsession go with some people?
