I used to love supercars and championchip sprint when I was younger and cant forget micro machines, what others do any one on the forums recommend for old time sake.
I enjoyed playing MM a lot more because the playing field between cars is fair; every car has the same stats and it came down down to whoever cuts the other off the map. Because TTR isn't top-view, you can't play the game of cutting people off the map. It's just another arcade racing game. The upgrades don't really make the game much more refreshing. The way I see it, it's a short-term obstacle when dealing with opponent's weapons, but a few grinds later, you'll have amassed enough money to make your car so fast that the game becomes much less challenging.
