No matter what some people want you to think, out with the old and in with the new doesn't actually get rid of the old shit. If ever you do make a new friend, you don't get rid of or replace your old friends with the new friend or friends unless you were a born a fool, no matter how long ago it was you were born.
The newschool shit isn't better than the old shit. Buzz Lightyear wasn't better than Andy's other toys, his ego made him think that he was.
New School Gaming is a style of play for TTRPGs that seeks to emulate video game play. It has a focus on railroaded play where player decisions do not affect the outcome of the game. Instead of having a risk of death for the characters, the game is dumbed down and made easier so that winning is assured and nothing difficult is encountered. Use of your imagination is discouraged and skills related to being able to think outside the box are not needed.
New School Gaming is all about all round pegs for all round holes, total uniformity and nothing unique.
Short-hand for the word floccinaucinihilipilification, meaning the estimation of something as valueless (encountered mainly as an example of one of the longest words in the English language).
