You could always download the demo and see if it is something that you can get into or not. I'm not sure how up to date the demo is, but it will atleast give you an idea what to expect. Yeah, visually it's very basic, but as long you find the gameplay good I think you should be able to enjoy it. I've had lots of fun with it and still play it sometimes (have the game for years now), even though top-down isn't my favourite perspective either. Development of the game is pretty slow (on the feature front), but they release new updates quite often.
