Exactly, so don't say something's not helpful when you're not offering a better solution.

That's still the opposite of what we should be doing.  Instead, we should show Nintendo that half-assed, shoddy ports are not ok; especially at full price.  Games like Returns and Luigi's Mansion 2 just piss me off when all of the effort that went into the excellent Metroid Prime Remastered was only $40.

You are on the right track.  If you want good DKC games in the future what you should actually do is buy new, sealed copies of Tropical Freeze about a week after DKC Returns releases.  It would be even better if someone could get a whole movement going to buy Tropical Freeze at this time and boycott DKC Returns.

Nintendo does notice when one type of game in a series is selling better than the other.  For example, BotW has sold far better than Skyward Sword on the Switch.  This guarantees more Zelda games like BotW will be coming.  By the same logic if they see Tropical Freeze selling a lot better than Returns, then they will get the message.
