The reason me (and probably many others) want collisions in TM is because of the replay possibilities. So many games these days are not only leaving the PC in the dust in favor of technologically inferior -consoles-

but they're also slicing out a number of features in order to make the games 'fit' on the console's limited memory--such as replay features. TM is not only PC-exclusive, but it cuts nothing from the features--in fact, it has a number of features games have -never- had, such as a full video-editor, the ability to build custom cars from scratch, and a full scripting interface to create your own flavor of Trackmania. Like I've said before, if Trackmania were to add collisions, it would go from being one of my top racing games, to the only racing game I would ever own. Period.
