Why pay for the rest of the episodes

I really liked the game when I bought It I thought that you dont have to pay for the rest when I finished episode 1 I went to download the second I then found out you have to buy it I got real y mad why pay 12.56 in total to be able to play the rest.This is a tip for the telltale people just merge all the games and put the price at 6.99 so then more people will buy it and you will get more money. And to all the people that will buy this game just save your money and dont get this game dont be tricked like me
