What you wouldn’t get are people that ended up not liking the game enough to buy it later who might have dropped the money before they didn’t know they wouldn’t be in love with it (Sword of the Stars in my case).

I would argue that it is a good approach. If you buy some product and you realize you don't like it you can return it back to the retailer. Computer games somehow are exception from that (ok, usually you can return them back, but it's a bit of a hassle). So if the publisher/developer don't mind not getting money from people who tried the game and didn't like I support them in that decision.
