My kids bought this recently, because it's Dr Who! There's nothing else out there for Dr Who fans to play so they were keen to see what thrills this game offered. Everyone had a go (including me) but very soon each bored of it and went off to watch some paint dry as it's much more entertaining - unless, of course, you happen to be fanatical about playing Top Trumps card games. I persisted through several levels to give it a fair chance, just in case the kids were missing something. On each level or round the Dr takes on a different opponent and you compare category values on your cards; highest value wins until either the opponent or the Dr takes the game and wins either or both a mini game (very basic logic/memory types) or a cheat. There's no animation; you just see two cards on screen and new cards are revealed after each play. There's opportunity to use various power-ups to increase your own or reduce your opponent's card values, etc. Once you've defeated an opponent you are taken to the next round where you take on another opponent and play the same game yet again, trying to make sure you get the highest score each play until you win the round. Only thing is, opponents are limited so you don't get to take on the whole range of your favourite baddies, and (oddly) opponents include Martha Jones and Captain Jack.
My kids also collect the Top Trumps Dr Who cards and they have dozens more than the limited number of cards used for this PS2 game. I loathe Top Trumps cards (because, as a parent, I have to pay for the blessed things and see them only as a cinical and exploitative marketing scam preying on children - see, told you I loathed them!), but with this game even I was soon able to memorise which were the higher, winning cards and so begin to win most rounds. I would imagine that a young child (with twice as many grey cells as I have left) would be able to memorise them much quicker and easier.
Believe it or not, I now loathe this game as much as the cards - and for the same reasons. Please explain to your kids that the front cover DOES NOT reflect the quality or content of the poor excuse for a game that this is. (Shame on the Dr Who franchise for ever allowing this game to be created). Much as I hate to say it, treat them to a couple of packets of Top Trump Dr Who cards instead.
