It was playing Digimon World 4 with a kick ass friend. We got the bright idea of going after the signiture weapons for both our characters (Beelzemon and WarGreymon). For those of you who don't know, you have to beat the Hard Difficulty w/out turning of the power and then go to the very first area and fight "King" Numemon.
The Dreadnought took over an hour to get through, both times. We almost died fighting the final boss. We leveled up alot. We started Sunday morning around Lv. 110 and finished Monday morning at Lv. 137 (Beelzemon, Me) and Lv. 133 (WarGreymon, Friend). Sure, that may be enough for some people, but not us. We started a game in Ultra Hard difficulty and made it to Apakarimon (Boss of Death Valley), before we realized we were tired.
