ThreadSteamWorld Quest - Official Launch Trailer - Out on April 25th
He's not wrong about the overland, but I don't think that's what the game is about. It's about the battles using the card system. There are more than 70 different monsters (though you only see some of them once).
I usually buy physical because there is a higher probability of getting a deal on them. Those discount programs are slowly going away though. I love the convenience of physical, but the few bucks extra per game I'm paying each time is not really worth it to me to switch over completely.
I'm not a regular GameStop customer, but there's an entire subset of gamers that buy their consoles and games their religiously. This will definitely hurt those people, even if only temporarily, if GS closes their doors.
