The closest I've come to spending money on a game that wasn't an MMORPG was Temple Run 2 when they offered Usain Bolt for a limited time, lmao. I fortunately have not gotten into the usage of DLC in games. Of course, I see the appeal, and if I was extremely wealthy, I would utilize it. I'm not, though, and don't see the point when you can still get through the game without it. If I spent money on a console game, it would have to be something I wanted horribly bad, because otherwise I wouldn't even consider purchasing it.
Now, I'm sad to say that my mindset with console games did not carry over to my love for MMORPGs. Back in the day when all I did on a computer was go online and play these games, I begged my parents for money to get more in-game cash and pretty my character up with rare equipment and upgrades. I probably spent $100 on MapleStory a few years ago. That was definitely a dark time, haha. Eventually, I got out of that obsession and now I never spend money on games. I'm relieved that I changed, because now I realize the uselessness of what I was doing!
