There's a difference between something having a slow beginning and something being unplayable/unreadable/unwatchable. While it ultimately comes down to personal taste, sometimes it's really kind of senseless to waste your time in continuing. If it's just a slow plot, then yes, give it a chance. It might pick up. If you absolutely can't stand it at the fundamental level, then you might just want to spend your time doing something more productive or enjoyable. With books, if the author's style of writing is annoying, chances are it will annoy you for the rest of the story. With movies, if the acting or writing is annoying, that will be all you think about. With games, if the gameplay is irritating, it will effect you for the rest of the game. Regardless of how well everything else is working. Sometimes it's redeemable, but sometimes... no.
So there's nothing inherently stupid about putting down a game/book/movie early if you're annoyed with how it functions at the core level. And if it's still on your shelf, you can always try it again later when you have nothing better to do. And if you returned it, oh well. More money to be spent on something you'll really love. Which isn't to say I immediately throw away any game I'm not enjoying, but there are judgment calls to be made when it comes to that kind of thing. Don't regret that I stopped reading Eragon before I hit the 30 page mark, for example (that was after considerable effort was made to give it a chance).
Sometimes, you just don't get along with a game/book/movie. Better for you to leave an abusive relationship than continue it.
I would like to congratulate you on being the only person to get my point. Hooray!
And yes, I can take "slow gameplay". As long as it doesn't putz around for too long, I can keep going. But the
gameplay and overall "here, let's show you exactly what to do for each step of the game" feeling started making things annoying.
After a point, Link's Awakening, one of my favorite games, stops tutoring you. You're supposed to figure things out (or use a manual, whatever). Oracle series games started making the fedex quests between dungeons longer and more annoying to do, to the point more time was spent running errands for somebody than actually playing though the dungeons and overall it just got tedious after a while. This game has you
sailing and
running around like an idiot for a long, long time to accomplish anything.
There are certain game mechanics that will piss me off. The same ones won't piss you off. It's just how things work, and if you start calling anybody "stupid" for their opinion, you have a problem.
