Since I only started barely two months ago, I have many reasons to continue playing. Loot, stats, challenges. But mostly, I have had a ton of fun trying to figure things out about team play and group dynamics, with some of the different players I now frequently play with. We laughed ourselves sick with using things like the Disruption bubble (Keeper) combined with a Saarabas with upgraded tara-shield. The slow motion "stun dance" is ridiculously funny.

Most of these trials of combining different abilities, are done on Nightmare now (though we do spend significant time still in Perilous). Considering we have some squishy players (myself most notably), working out the roles for the team members has been oddly satisfying. I can't produce seriously high damage numbers, most of the time (due to the lack of high attack and crit chance), but I have found different classes I can use in a support capacity, AND have concentrated on aiding in team combos (when applicable).
We can even appreciate some of the funnier glitches (and we have had a slew of them through our many game plays). Snapshots are always welcomed.

Fallout may eat in to some of my play time of DAMP (and DAI single player), but I will still be playing often, I suspect.
