Problem is, there's always people with differing opinions who wander into the game, say something like "WTF thiz gaem sux so bad" and whine about how much of a waste of money it was.

Sure, they may be challenged in all sorts of depressing ways, but they can have an opinion, wrong as it may be, too.
Best suggestion I have is to try the (free) demo, see if you like it, and if you think it's fun, buy the game.
If you like the game, THEN subscribe.
Do not skip stages.
Do not whine.
Do not pass go.
