Oh oh oh you absolutely must play the Phoenix Wright games, I think you'd like them ♥. Like centralremote said, it's best to play them in order, since the first three games at least have an overall arc thing going on (and the fourth takes place after those three). The UK release schedule was crazy in that they released the fourth game before the third and for ages it looked like it wouldn't be getting the third, but we did eventually get it. Right after a friend had sent it me from the US, naturally.

The first game is still kind of my favourite, though :x I bought my DS in the first place to play Phoenix Wright, this is a decision I have not regretted once ♥. (AND NOW THE NEXT GAME IS GOING TO BE OUT ON THE 3DS AUGH WHAT DO I DO.) (Buy a 3DS, I suppose...)
