I have reasons to both thank Gravity and reasons to curse them. On the one hand, they made Ragnarok Online, which I regard lovingly as the first MMO I ever played. I spent many hours in Rune Midgard in high school, grinding away to level my spear-based Knight, and I look on those hours fondly. For this I thank them.
They also, however, made a free-to-play server during my senior year... this is a seriously unfortunate development.
The worst may be over, however: though I spent about 11 hours the past few days gaming rather than working (please, I know how dumb this is, no need to berate me), I may have shaken the MMO bug thanks to a design flaw! Designers take note: if your going to implement a cool new Gunslinger class in your MMO, please make sure there's more than one freaking merchant in the entire game world who sells bullets. Making low-level players glued to a lonely town miles away from anything else because it's the only place they can get supplies is remarkably ill conceived.
But again, I suppose I must give credit where it's due. Thank you, Gravity, for giving me a good reason to stop playing your game and go back to work. <3
