I spent $180 boosting my character (bard, because white mage is too boring), skipping Heavensward for Stormblood, and resubbing. Sad CAD killer conversion.
I play this game for 30 minutes a week and I'm still level 61! At least bard really is more interesting than white mage. Done worse though--I bought $100 worth of Hearthstone cards for the Un'goro expansion and played like 4 games that season.
And this is exactly why I'm wary of spending any money on video games/consoles these days... Well, the expansion was fun, and I genuinely enjoyed the story and the two levels I got. But the last time I opened the game, I was in too much physical pain to play (eh, every so often everything just hurts, probably allergies). And that was pretty much the end for me.
Boy that new Smash Brothers game looks tempting, though...
