I've not played Ticket to Ride much, but I feel like I have a grasp of it. Like the description says, you can learn how to play in a matter of minutes but it will take a lifetime to master.
The basic idea of the game is to build more train lines than your opponents, this is done by matching the colour of the line with the colour of a train cart. You get different coloured train carts out of a deck of cards.
The game has a very good built in turtorial video and lessons which explains this all in an easy to understand way. It can look very daunting at first but it soon becomes apparent that it is a very simple idea behind it all.
Sadly from my 3 hours playing, I haven't once been able to find a match online against anyone, mainly because I get an ingame error message when ever I try and find or start an online game, so my review is based purely on the single-player aspect, and while I haven't actually won a game of Ticket to Ride, I did enjoy my time playing.
I'm not sure who this game is aimed at, but since there is a physical board game for Ticket to Ride, I'd say only pick this up if you enjoy the board game, but I can't really recommend this game for anyone else, £6,99 is a bit much for this, and £14,99 for the complete pack is utterly silly.
