I was playing through the Etrian Odessey 4 demo to see if it caught me. It lets you play up to level 10, which amounts to a few solid hours of gameplay. It then lets you transfer your game to the full version upon purchasing it.
Well, turns out that yesterday I got so addicted to the demo that I totally forgot that the sale ended at noon!!! I reached level 8 and then went to the eShop (literally checking it a few hours earlier that morning) only to find it back up at $30.
Oh well, guess I'll have to wait. Maybe I'll start fresh with a brand new party while I wait. They really need to stop scattering all these sales around. Wish it was Nintendo-based, not developer-based. It's a chore just keeping track of all of them.
