Never played the others (would have liked to have a go though just to see what they were like), I loved V-Rally 99 Edition.. finished it with 100% completion.. was part of a great Christmas for me coupled with Goldeneye 007 as a present for me and my bro ..couldn't get enough of them..
..the game I got least enjoyment from was probably when my friend brought pokemon stadium with him to my house (and I'm NOT a pokemon fan..at all..) ..found it all very boring.. apart from a couple of the minigames..
..and I have played Carmageddon 64..
