I couldn't quite decide from your description whether or not this would be something I'd enjoy, but I went to Steam to look at it anyway. I don't think that it's quite worth the $20... but the 2014 version is on sale now for a grand total (with sales tax) of $0.74. That's worth giving it a spin, even if I am going to inevitably end up spending an hour looking for an air filter or something because I don't know my way around car innards very well.
