Well guess I'm in the Ryu Makkuro side on this! You don't need to be a rocket scientist to know when the game is not bad but you are
If I'm losing every race I try to practice a lot and if I still failing I see how other ppl do(gameplays, friends etc). If someone is doing great at the game and I'm not it means I'm not good enough so the only way out is keep trying or give up! Hell even with bad physics some ppl do better than me soooo it means I need to get better even if the game still has some flaws it's still doable you know.
When the game is finished with perfect physics it will be just a matter of skill so I guess it's better to just leave the way it is in that we choose our difficult mode and maybe create some cute friendly robot to say some friendly advices for ppl that can't understand why they are losing or something
