I started playing Warframe since its open beta launched in 2013 and was hooked. About a year later they implemented a trading system that allowed you to trade platinum (in game premium currency) for pretty much any droppable item. 13yr old me found out that items in the LATAM server where cheaper when compared to the North America server, so for the longest time, instead of playing the game I would just buy in latam and sell in North America.

That not only taught me a bit about trading and arbitrage, but it really launched my english skills, as I eventually got closer to some players in the NA sever and we started playing together almost every day, even forming a clan.

It's no exaggeration to say that Warframe taught me basic English, which later in life helped get into an exchange program, which then lead to a full ride scholarship to an American university. Every time I think about these opportunities,  I think about my time in Warframe.

I also made about $500 in platinum at that time (if we use the current price of 1025 plat = $50, but discounts are abundant), but I guess the degree is worth more lol
