Drakengard 2

It's easy to get in the thousand's with Urick. I'm on my second playthrough and the enemies do seem to get a little bit harder. I've gotten a 4000 combo with Urick, but a 5000 combo with Nowe, attempting to level up the Silver Butterfly, Nobuyoshi, and SealKnife. Of course it does get a good bit repetitive, but yeah, the additions to the story on the second playthrough enforce the will to keep on playing, especially for the additional ending. I remember when playing the first game, I got all the endings except for the last one, which required me to get about 97% of all the weapons. Of course, I didn't want to waste my life getting all those weapons and leveling them up to 4, just to fulfill the completion, but yeah, it got overly monotonous in the first game. The second game is a great paint job over the scratches of the first, and calls for much more than the first game. Of course, the first game had OODLES of soldiers to kill compared to the second game, but hey, it's in the challenge no?

Jam it back in, in the dark.
