If they feel they've made loads of profit already and want to drop to a reasonable price then go ahead. It's their game they can do what they want. I'd rather this carry on then the game staying full price for years so be thankful.
But it's right after the damn Christmas sale that was for higher than the price drop. You gotta find that at least a little bit dastardly. (even though in reality it's a lot dastardly)
