Having a TSW route for Slovakia would be an amazing new experience, and could completely re-imagine the way we use TSW. In Slovakia many stations are both for passenger and freight, meaning a station like Žilina needs 3 shunting locos on-hand at all times. As a shunter your load could vary between incoming express passenger trains to remarshalling freight. For some more cash you’d be able to create more routes, say, Bratislava - Žilina - Košice, Which is an express route often featuring modern and classic motive power. Buying more routes - say that the base pack includes a double decker route to Trenčin, a light rail bus route to Rajec and a freight route to nearby container terminals/coal mines. The rest could be easily added on to have more trains to more destinations.
