I think a lot of people enthusiastically have started an engine supplier, but I think we/they already regret it, because we realized if we use another people's engines, we don't have to use these engines, if they're not so good, but we can us them for a little money and we have a lot of money, so it isn't problem, but we don't have to pay much tokens or wait much like the suppliers.
I think the two side would be more balanced, if we could ask for tokens in exchange for engines. It's a bit complicated because there isn't so many tokens/race, so I suggest to make a more-race contract e.g. 5 race, and it's possible to set it from 2 to 5 tokens or something simular...
Thanks
