After I finished the main storyline of Dragon Quest IX, and some side stuff, I unexpectedly got tired of it, and grabbed a Yu-Gi-Oh! game to satisfy my new craving. After playing through the story about 3 times, I got bored of Yu-Gi-Oh!, and when I went to a friend's house, he asked me to show him the "Slime Hill," a place filled with nothing but slimes, allowing you to find members of the Metal Slime family (who have high evasion and defense, immunity to magic, have the potential to run away fast, but give monstrous amounts of experience). So, I obliged him, let him into my world, and we went slime-hunting.
 
Then, when he left, I got a bunch of quests. Wi-FI Quests. The quests I normally can't get because my Wi-Fi is WPA instead of WEP. It surprised me that if I connected with someone who connected to Wi-Fi, I get their share of the quests and material to go bonkers.
 
Not to mention a treasure map.
 
So, my love of Dragon Quest IX rekindled, allowing me to double my original playtime of 60 hours, making me go through grottoes, level up more, take on these side quests (both in-game and Wi-Fi) and overall, have so much fun that I wondered why I stopped in the first place.
 
Has anyone else gotten tired of DQ IX and then jumped back in? From my point of view, it's hard not to.
