I don't know what you have against the mini-games. Okay, DNG isn't really my cup of tea, but I enjoy the others.
The reason why DPC integrated mini-games into BaDIK is obvious. How is the player supposed to develop a college feeling if the player doesn't have to take English, math, IQ tests, etc. How these players really immersed themselves in the college life of BaDIK, without the party games. Even the future snowball mini-game has its purpose.
The mini-games help to intensify the experience of BaDIK. I think that's good. Furthermore, I assume that there could be consequences if you play BaDIK without mini-games. Why?
With mini-games, the BaDIK player decides the outcome of these mini-games. If they are disabled, DPC decides the outcome. Think about it.
