I think this one asks you to pay for it after a bit. Not that there's anything wrong with that. Just felt bad about getting a little bit in, and then being hit with a decent pay wall.
Like, I'd bet "Pay $10 if you like it" / ReaperWare would earn this person literally an order of magnitude more money.
What does this mean? All I found on the Google was a company that produces sim racing gear.
Wait, I'm the first to say that? That should be a thing.
I found a pricing dialog after clicking “buy a license”, it said that six months of full access to the game costs $35.
