It's a hot summer day and you and the other neighbourhood kids hear the ice-cream truck
(mogstation) come around the corner. You all quickly run to your parents to give you some money to buy ice-cream
(playing FFXIV). They only give you enough for a plain vanilla cone
(monthly sub) but you don't care because you get to enjoy ice-cream today. You go out and buy your plain vanilla cone and you are enjoying it. Then one of the neighbourhood kids buys a double chocolate dipped, chocolate and vanilla swirl, waffle cone with crushed nuts, caramel drizzle and a cherry on top
(monthly sub, retainers, exclusive mounts, exclusive glamours). You both get to enjoy ice-cream
(playing FFXIV) but one clearly has a better experience simply by comparison. The other kid with the plain cone can either deal with it and just be happy they get ice-cream or more commonly, get jealous, cry to their parents for one just like their other kids and now the parents have to buy it for them
(coerced sales).
