So I had this game on, I think PS1, that I can never remember the name of.... I guess a part of the game was sort of like Carmageddon, you could drive around and run over things, I remember running cows over, but you could also go into places in a first person shooter mode to do missions and kill people with guns.... I really loved this game but could never remember it's name, a few years ago I found it but lost it again. I'd love to play this game again!
I also can't find this PS2 game, I used to own it but sold it/lost it/broke it, it was a destruction derby/race game/time challenge etc with free roam, you chose 1 car at the start to use, then you would do races, demo derby, etc to earn money to buy new cars, upgrades etc. The upgrade shop you had to drive to to buy the stuff and cars. I strongly remember this song playing https://www.youtube.com/watch?v=DA2wjmB91ws I think the cover had an orange car on it, but I believe the game had 2 names...
EDIT - AHA! I found the second one, it's called Driven to Destruction, or Test Drive: Eve of Destruction. Great game!
