And I've been happily collecting achievements. Well, I was until I realised what one of them involved:
Humans Gooood - Play a 4 way local Multiplayer race in which all the humans beat all the AI.
Seriously? Who's going to be able to get this? Not only do I have to get three people to come over to my house, they have to bring a controller with them AND be good at racing games. Possibly THE most annoying achievment I've ever come across. It almost makes me want to switch my Hydro Thunder Avatar t-shirt to something else. But then I remember the level with the giant Viking, and the epic jumps over canal boats... Hydro Thunder Avatar t-shirt stays.
