Nope. It's about ubiquity, and when it comes to cookies there is nothing more common than chocolate chip. All evidence you just gave in favor of the chocolate chip cookie is evidence for the greatness of ANY cookie. What about double chocolate fudge? The dough tastes better raw, the cookie goopier when warm, and goes just as well with milk.
Saying the chocolate chip cookie is the greatest is like saying the Toyota Corolla is the best car. It's reliable, has four doors, gets good gas mileage, and has a reasonable amount of cabin space. But there is more to cars than that. There is more to life than the Toyota Corolla, and there are better cookies than the chocolate chip.
Also, Tiny Tina is not a reliable source and I'm a little concerned I needed to say that.
-SILLY Rant-
#1) How DARE you express ANY doubt of Tiny Tina (she makes things go BOOM).
#2) If, as you say, Chocolate Chip Cookies are EVERYWHERE then that WOULD indicate that they ARE the Bestest. If some other (lesser) cookie were to be considered as better then that would become more accessible then the GLORY of Chocolate Chip Cookies.
#3) I noticed no objections of including EXTREME close-ups of the MC's left nostril. As such I will add you as a supporter.
#4) You bring in a RARER Cookie called Chocolate FUDGE. Well, it is rarer thus NOT as good, since if it was equal or better it would be MORE available. Yes, there may be SIMILAR benefits to the WONDEROUS Chocolate Chip Cookies, but to declare it better is just SILLY.
#5) You are FAR braver then I to suggest Tiny Tina might NOT be a reliable source. I mean, for all we know she MIGHT be watching.
#6) To be honest I just want (SEXY) fun with cookies (NOT Oatmeal Raisin Cookies, they are EVIL). My obsession started a LONG time ago with a silly suggestion in another game, and now I Promote the inclusion of the DIVINE Chocolate Chip Cookies where I can. A series of (SEXY) fun scenes that begin with preparing the Dough, MORE (SEXY) fun while they bake, and EVEN MORE (SEXY) fun while eating them fresh from the oven would be AWESOME.
#7) While it would NOT be as good the series of scenes mentioned in #6 might be done with cake batter (and FROSTING) or something similar. The (SEXY) fun is as much in the 'Interesting' (SEXY) methods used to clean the mess as it is in the Chocolate Chip Cookies (though the Chocolate Chip Cookies make it better).
#8) As often happens my list has gotten VERY long so I will end it here by saying Chocolate Chip Cookies ARE the best. Should you have a different opinion then that is fine (I'm telling Tiny Tina).
-End of Silly-
Yes, this IS silly, but like I said a series of (SEXY) kitchen scenes built around Chocolate Chip Cookies (or something similar) MIGHT be interesting and FUN. Yes, I promote the inclusion of Chocolate Chip Cookie Content because I think one or more scenes like that WOULD be GREAT. NO, I will NOT risk the danger of Tiny Tina even thinking that I doubt her or the AWESOMENESS of Chocolate Chip Cookies.
Just a thought.
P.S. This is presented for FUN. I am not attacking you or anyone else for Cookie Preference (unless it's Oatmeal Raisin cause those are NASTY).
