Suden Temptation- Quick Battle: Defeat all the Warriors(Soulcalibur V)
Flame Distortion [arcade] Defeat Order Sol (Guilty Gear XX)
Deity - Complete all the episodes with an S Rank on Hard (Asura's Wrath)
The Dark Soul - All achievements (Dark Souls)
Forging Master - Upgraded 30 Weapons to their maximum Level (Nier)
^I think these were the only achievements that really gave me that sensation of accomplishment.
The first one though takes the cake by being not just extremelly time consuming but also a pain in the ass.
