No idea why, but lately more and more quality titles are hitting shovelware-esque prices on the eshop.
This is the new all-time-lowest price for the Australian-made Agent A.
79, 7.7 on Metacritic
Headliner: NoviNews has a 75 and 7.6 on Metacritic
While you're digging around in the bargain bin, also consider:
80 Days (has a metacritic score of 84, 8.1) for $3.65 (normally $18.29)
And This Strange Realm of Mine for $1.99 (just finished this myself and had a fantastic time).
Agent A is terrific, highly recommended.
