I still play the game, and indeed have "OMSI 2", OMSI's sequel game.
You can drive articulated vehicles in OMSI 2 and there's a few more odd features such as trains, trams and other forms of transport being more integrated into the game, but other than that it's buggy and not worth updating from OMSI for.
@jaimz13: if you're looking for new buses - albeit not in Go North East livery (there are some Stagecoach and Arriva repaints on the market, however) - then I'd strongly recommend downloading the Volvo 9900HD. Awesome drive - feels different to drive compared to ordinary buses, and there's a few features on there (such as a breathalyser which you have to use in order to turn on the engine).
