I like the idea of this game and the potential and I realize it's pretty early, but the biggest issue you'll have? Is making people pay money and then making the weight for something like fuel. If I buy it? It should just appear, otherwise you're making us pay to just wait in game. It's a deal breaker really, and it feels a bit cheap. Like, hey wait here as we suck your play time, which cost money in the long run.
And in a way it's in your benefit to have players weight to do things right? A little delay here and there and keeps the coming back. The lodading times, they need to be better too.
There should be no waiting for things - no loading from point A to point B. Just some things I thought of in the first 5 minutes or so of the game.
