I have noticed over the last year or so that the games by this developer run slowly and with lots of lag - so much so they can't be enjoyed. Other games run fine .
Starting with an American black cab driver wishing me to have a good day in London was not the most auspicious start and while I realise that the biggest market for these games is the USA it would be nice to get apposite accents and references i.e. tube carriage not train carriage however the developers pulled me back in with the good gameplay and loved the Dr Who references near the start.
As others have said - very short and confused. Picking up items before you even realise you need them and virtually no storyline. Bought it half price but I still feel shortchanged..
Based on the free trial this game is old style with no real fine tuning preferences and without the classic HO puzzles. The storyline is confusing and one rushes all over the place without and real logic. As another reviewer said if it wasn't for the map showing the areas to visit next I would have given up at the start.
